If allergic reactions are caused by antibodies binding to allergens, why are the responses localized (limited to a given tissue like a runny nose or upset stomach)?

    Allergic responses arent tissue specific.
    Allergens interact directly with tissues and cause inflammatory response whereever they fall.
    Antibodies that respond to allergens are attached to mast cells, which are located in tissues, not circulating through the bloodstream.
    None of the answers is correct.
