Question

The type of antibodies produced during an immune response to allergens as dust and pollen grains in a person is:

• A. IgE
• B. IgA
• C. IgG
• D. IgD

Hint:

IgE is the key antibody in allergic reactions, binding to mast cells and basophils to trigger histamine release in response to allergens.

Answer 1

The Correct Option is A

Allergens like dust and pollen trigger an allergic response, which primarily involves IgE antibodies. IgE binds to mast cells and basophils, leading to the release of histamine, causing allergic symptoms. IgA, IgG, and IgD are not primarily involved in allergic responses.
