A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Step-by-step solution
Allergy is the exaggerated response of the immune system to certain antigens present in the environment. Common examples of allergens are mites in dust, pollens, animal dander, etc.
Symptoms of allergic reactions include sneezing, watery eyes, running nose, and difficulty in breathing. Therefore, the Assertion is true.
Allergy is due to the release of chemicals like histamine and serotonin from the mast cells. The antibodies produced to these are of IgE type. When a sensitized person is exposed to an allergen like animal dander, it interacts with IgE antibodies bound to mast cells, triggering the release of these chemicals which cause the symptoms. Therefore, the Reason is true and correctly explains the Assertion.
