Question

Sensitivity to any allergen could be because of

• A. Deviation from the process of immunity
• B. Age of the person
• C. Eating habit
• D. Rise in environmental temperature

Answer 1

The correct option is A Deviation from the process of immunity

Allergy is the condition when the body or the cells become hypersensitive to the foreign agent. The allergen causes the proliferation of the T helper cells and memory cells. In the condition of hypersensitivity, there is inactivation of these memory cells which is referred as a deviation from immunity. The memory cells do not recognize the antigen/allergen and fail to stimulate the cells to produce antibody. There is secretion of histamines which cause the allergic symptoms.

So, the correct answer is option A.
