To answer this question, you need to understand the role of insulin and the organs involved in its production and release.

Insulin is a hormone produced by the pancreas, specifically by the beta cells in the islets of Langerhans. Its main function is to regulate the level of glucose in the blood by facilitating the uptake of glucose into cells.

Insulin is not injected into the intestines. Instead, it is typically injected subcutaneously (under the skin) into fatty tissue, such as in the abdomen or thigh. From there, it is absorbed into the bloodstream and circulated throughout the body.

Based on this information, we can eliminate options A and C (Pancreas and Stomach) as incorrect.

The liver plays a role in glucose metabolism and storage, but it does not produce or release insulin. Therefore, we can eliminate option B (Liver) as incorrect.

The correct answer is option D (Gall Bladder). However, it is important to note that the gallbladder does not directly inject insulin into the intestines. The gallbladder is responsible for storing and releasing bile, which helps in the digestion and absorption of fats in the small intestine.

Therefore, while option D is the correct answer, it is not directly related to the injection of insulin into the intestines.
