Health is defined as a state of complete physical, mental and social well-being. It depends on three parameters physical, mental and social. It is a dynamic condition resulting from a body's constant adjustment and adaptation in response to stresses and changes in the environment for maintaining an inner equilibrium called homeostasis.

The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution. 

 An adaptation is a change in organisms (plants and animals) that help to survive in their particular habitat and reproduce in the changing environment. It is necessary for organisms to survive if its surrounding change. Thus, the correct option is D.

Hay fever is a form of allergy due to the pollen of grasses, trees, and other plants, characterized by inflammation of the membrane lining the nose and sometimes of the conjunctiva.

An acute disease is a disease which mainly occurs for very short duration and it is not severe. It can be easily cured by regular treatment and it is not life threatening. Example- cough and cold.

The diseases which are present from the birth of an organism is known as congenital disorders. These diseases have genetic causes and are transmitted from parents to offsprings. Hence, these disorders are inherited from the parents within the womb or after the birth of the organism. Thus the correct answer is option D.

Communicable diseases spread from one person to another or from an animal to a person. The spread often happens via airborne viruses or bacteria, but also through blood or other bodily fluid. The terms infectious and contagious are also used to describe communicable disease. For example- HIV/AIDS. 

The lungs may be infected due to the bacterial agent causing Pneumonia. This is the infection in which there is a production of large amount of mucus and so the person suffers from coughing and breathlessness, due to blockage of the air ways.

There is mood swing which results in two type of moods. There is an extremely high energy level mood and a depressed, sad mood. The conversion and the regulation of moods are lost in this disorder.

Epilepsy is a group of neurological disorders characterized by epileptic seizures. Epileptic seizures are episodes that can vary from brief and nearly undetectable to long periods of vigorous shaking and there is unconsciousness. It is generally caused by brain damage, which may be due to head injury or metabolic disturbance or since birth. Epilepsy occurs due to abnormal electrical discharge from neuron of the brain.

Adolescence refers to the period of human growth that occurs between childhood and adulthood. It can be classified into three stages early, middle and late. 

Schizophrenia is a mental disorder characterized by abnormal social behaviour and failure to recognize what is real. The word schizophrenia translates as 'splitting of mind.' The symptoms include false beliefs, unclear or confused thinking, auditory hallucinations, reduced social engagement and emotional expression and inactivity. It is non-infectious and non-communicable disease. 

Epilepsy is the condition in which there is formation of seizures in the brain. The anti-epileptic drugs are used for the treatment of this condition. The most common type of anti-epileptic drug is Acetazolamide. The tablets are preferred for the different form of seizures like focal and clonic. 

Mental illness is a condition that affects a person's thinking, feeling and mood. Depression, Schizophrenia are associated with mental illness. The psychological syndrome is characterized by sadness, hopelessness, low self-esteem, decline in interest.

ECT is the abbreviation for Electroconvulsive Therapy. ECT is a psychiatric treatment which is suited in some cases and can bring about dramatic improvement in severe depression. In this, electric currents are passed through the brain, intentionally triggering a brief seizure.

Hemophilia is sex linked recessive disorder. Gene responsible for it present on X chromosome and only expresses in dominant state. Out of four children of john (hemophiliac male) and Jane (normal woman), both the girls Molly and Mary become heterozygous for hemophilia as they got hemophiliac X chromosome from father only, which they pass on to their children resulting sons with hemophilia expressed and daughters are either normal heterozygous for hemophilia. The boys Mark and Mike are normal as they don't get hemophiliac X chromosome from father and when they married with normal individuals, all their children would be normal.
