Correct Answer: Humoral immunity (IgE antibodies)

Step 1: Understand that allergic reactions occur when the immune system overreacts to a substance, like pollen.
Step 2: Identify that the immune system has different types of responses, including humoral immunity and cell-mediated immunity.
Step 3: Recognize that humoral immunity involves the production of antibodies by B cells.
Step 4: Learn that in allergic reactions, a specific type of antibody called IgE is produced.
Step 5: Conclude that the primary immune response involved in allergic reactions, such as the one to pollen, is mediated by IgE antibodies.

Humoral Immunity – A type of immune response that involves the production of antibodies by B cells, particularly IgE in the case of allergic reactions.
IgE Antibodies – A class of antibodies that play a crucial role in allergic reactions and are responsible for mediating responses to allergens like pollen.
Allergic Reactions – An exaggerated immune response to a substance (allergen) that is typically harmless, leading to symptoms such as itching, swelling, and inflammation.
