Hay fever or allergic rhinitis is the allergic response caused by the hypersensitivity of dust, mites, animal fur or hairs. It is characterized by the running nose, sneezing and watery, itchy eyes. Whereas enteric fever is caused by the bacteria, Skin cancer is caused by harmful radiation i.e., UV rays and Goiter is the metabolic disorder. Thus, the correct answer is option B.

A- Anaphylaxis is a rapid, severe and generalized allergic reaction which may lead to death. Prompt administration of epinephrine injection can be life-saving. Timely administration of epinephrine injection decreases hospitalizations and mortality. 

Histamines are the inflammatory substances which are released by the mast cells and basophils during the allergic reactions. The excessive release of histamine may result in anaphylactic shock. Anaphylaxis is a type of severe allergic reaction which can result in the death of the person. Antihistamines are used for the treatment and cure of the allergic reactions.

Anaphylaxis is a type of severe allergic reaction which can result in the death of the person. The first or the primary treatment which is provided, is that the person is injected with epinephrine which reduces the basic symptoms. Antihistamines are used for the treatment and cure of the allergic reactions. The antihistamines are molecules which are similar in structure to histamine and block the H1 receptors which prevent the release and action of histamines. 

The T helper cells also known as CD$ _4^+$ release cytokines and trigger the activity of other immune cells.

Anaphylaxis, also known as anaphylactic shock is a serious allergic reaction that is rapid in onset and may cause death. It typically causes an itchy rash, throat or tongue swelling, shortness of breath, vomiting, lightheadedness, and low blood pressure. Common causes include insect bites and stings, foods, and medications.  The mechanism involves the release of mediators from certain types of white blood cells triggered by either immunologic or non-immunologic mechanisms.

Histamine causes a skin response. If you dont react to histamine, your allergy skin test may not reveal the allergy.

Hypersensitivity refers to undesirable reactions produced by the immune system including allergies and autoimmunity. They are usually referred to as an abnormal (aberrant) functioning of the immune system and these reactions may be damaging, uncomfortable, or occasionally fatal. Hence, hypersensitivity to an allergen is due to the aberrant functioning of the immune system.

Asthma is a chronic inflammation of respiratory tracts due to accumulation of immune cells to destroy dust particles or allergens. Yellow eyes occur in jaundice patient. Jaundice is hepatic disease. Mumps is a contagious disease caused by a virus that primarily effects salivary gland. Typhoid is a bacterial infection caused by Salmonella typhi. So, the correct answer is 'Asthma'.

A mast cell is a type of white blood cell that contains many granules rich in histamine and heparin. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems. Mast cells are primarily known for their role in allergy and anaphylaxis (shock). Mast cells play a key role in the inflammatory process. When activated, a mast cell can either selectively release mediators or compounds that induce inflammation, from storage granules into the local site.

• Anaphylaxis or anaphylactic shock is a serious allergic reaction that is rapid in onset and may cause death. It causes an itchy rash, throat or tongue swelling, shortness of breath, vomiting, lightheadedness, and low blood pressure. These symptoms are seen within minutes to hours. Common causes include insect bites and stings, foods, and medications. The primary treatment of anaphylaxis is epinephrine injection into a muscle, intravenous fluids, and positioning the person flat.
  
• A person stung with the bee is administered penicillin. The person died because insect stings and medication (penicillin) are the major causes of anaphylactic shock and death.

Allergic rhinitis, also known as hay fever is a type of inflammation in the nose which occurs when the immune system hypersensitizes to allergens in the air. Symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. Allergic rhinitis is typically triggered by environmental allergens such as pollen, pet hair, dust.

Histamine is an organic nitrogenous compound involved in the inflammatory response and has a central role as a mediator of itching. Histamine causes vasodilation of peripheral blood vessels due to which there is increased blood flow to the site of inflammation. It mediates the inflammatory reaction by the release of other chemical mediators of inflammation and causes redness, swelling etc at the site of inflammation.

In localized infection, redness and heat are due to increased blood flow at body core temperature to the inflamed site, swelling is caused by accumulation of fluid, pain is due to the release of chemicals such as prostaglandin and histamine that stimulate nerve endings.Histamine are mono-amine produced from mast cells and basophils these are stored in preformed granules, and is released to a number of stimuli these lead to arterial dilation and increased venous permeability. Prostaglandins are eicosaniod produced from mast cells they leads to vasodilation, fever and pain. Hence, localized inflammatory response at the sight of infection producing redness, swelling, pain and heat is due to prostaglandin and histamine.

Histamine is an organic nitrogenous compound involved in the inflammatory response and has a central role as a mediator of itching. Histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine is stored in cytoplasmic granules along with other amines and rapidly released upon triggering with a variety of stimuli. It causes the contraction of smooth muscle, dilation of blood vessels etc..

A mast cell is a type of white blood cell that contains many granules rich in histamine and heparin. Mast cells play an important protective role in inflammatory and allergic reactions. When mast cells are activated, they release mediators or compounds that induce inflammation from storage granules into the local site and promotes the inflammatory response. In allergic reactions, mast cells remain inactive until an allergen binds to IgE already coated upon the cell.

• Asthma is a common long-term inflammatory disease of the airways of the lungs.
• Symptoms include reversible airflow obstruction and easily triggered bronchospasms. 
• Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. 
• Asthma can be caused by Environmental factors including allergens, air pollution, and other environmental chemicals.
•  Hence, Asthma is caused by an allergy.
• So, the correct answer is 'Asthma'.

• Shock is a life-threatening situation due to poor tissue perfusion with impaired cellular metabolism, manifested inturns by serious physiological abnormalities.
  
• Anaphylactic shock is also called as Type I immunogenic reaction.
• Anaphylactic shock is characterized High permeability of capillaries causing loss of fluid from the blood.
  
• Anaphylaxis symptoms usually occur within minutes of exposure to an allergen. 
  
• The most common anaphylactic reactions are to foods, insect stings, medications and latex.
  
• So, the correct answer is 'High permeability of capillaries causing loss of fluid from the blood'

Allergies, also known as allergic diseases are caused by hypersensitivity of the immune system to typically harmless substances in the environment. The mechanism involves immunoglobulin E antibodies (IgE) binds to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. The release of histamine develops symptoms such as red eyes, an itchy rash, sneezing, a runny nose, shortness of breath, or swelling.

Hay fever (allergic rhinitis) is caused by grass pollen mostly but it can also be caused by tree pollen or weed pollen. Pollen is a fine powder enriched in protein released by plants as part of their reproductive cycle which can cause irritation in nose, eyes and throat. Symptoms of hay fever include sneezing, runny nose, itchy eyes etc. It is more common in spring and early fall. Hepatitis and dengue are viral diseases. Helper T-cells are immunity providing cells in the body

Flatworms are generally parasitic in nature and feed on the host organism's nutrition often causing disorders as a consequence. When it comes to parasitic infection, flatworms and roundworms are likely culprits. These two types of parasitic worms can be found in a variety of habitats. They aren't always visible to the naked eye. Tapeworms and flukes cause diseases in humans and their livestock, whilst monogeneans can cause serious losses of stocks in fish farms. Schistosomiasis, also known as snail fever, is the second most devastating parasitic disease in tropical countries, behind malaria.

Pollens are present in air. Excess of pollen are produced in certain seasons which causes allergic reactions in several human beings. The common allergic reactions are asthma, bronchitis and rhinitis.

Hay fever and asthma are the allergic reactions of the body to allergens. Allergy is the hypersensitivity of a person to some foreign substance coming in contact with the body. 

The nematodes or roundworms constitute the phylum Nematoda and have a pseudocoelom and complete digestive system. The partial, fluid-filled cavity inside the body of some invertebrates. Cnidarians have two different body plans. Both body plans have radial symmetry. A polyp, such as a hydra, sea anemone, or coral, is shaped something like a vase. Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates and have cavity only one opening to the outside which, in most cnidarians, is surrounded by tentacles for capturing prey. But Porifera does not have a gastrovascular cavity as it does not have specialized tissues and phyla with a true coelom and digestive system. The protostomes include the phyla Mollusca, Annelida, and Arthropoda but not porifera.
