Quizplus · Accepted Answer

Inhalation of allergenic pollen in a susceptible person causes the crosslinking of IgE sensitized mast cells, leading to the release of histamine and other mediators that trigger allergy symptoms.

Answer: B, C, E 
 Immediate anaphylaxis, binding to sensitized T cytotoxic cells, and immediate leukotriene release are all possible events that can occur as part of an allergy reaction, but they are not the primary event triggered by the inhalation of allergenic pollen. The primary event is crosslinking of IgE sensitized mast cells.
