Answer to Question 1

B

Answer to Question 2

An allergy is a hypersensitive reaction by the immune system in which exposure to an allergen causes the body to produce antibodies. Binding of the antibodies to mast cells causes the release of histamine, which in turn triggers a localized or systemic allergic response.
