Question

Quizplus · Accepted Answer

Allergy is defined as a hypersensitivity to an allergen, which is a substance that triggers an immune response in the body that leads to symptoms such as runny nose, sneezing, and itchy eyes. Option A also mentions a substance producing a hypersensitivity reaction, but it does not explicitly state that it leads to an allergic response. Option C is incorrect as allergens are substances that trigger an allergic response, not develop within the body. Option D refers to a specific symptom and not the complete definition of allergy. Option E also refers to a specific symptom and does not encompass the full definition of allergy.
