Answer
Option a:IgE and mast cells
Work Step by Step
Hay fever is an example of an allergic reaction to grass pollen.During the first exposure to pollen,B cells produce IgE antibody that adheres to the basophil surface.Subsequent exposure causes degranulation of the basophil and release of inflammatory mediators like histamine.Mast cells present in the lining of the respiratory tract also triggers an inflammatory response.
This explains that a combination of IgE antibody and basophils are central to hay fever.
