A)delayed
B)T-cell mediated

D)antibody mediated
E)systemic anaphylactic

Accepted Answer

A systemic, sometimes fatal reaction with airway obstruction and circulatory collapse is indicative of a systemic anaphylactic reaction. Delayed reactions occur hours to days after exposure, T-cell mediated reactions involve a delayed response by T-cells, atopic reactions are a type of allergic reaction that is genetically predisposed, and antibody-mediated reactions involve the binding of an antibody to an antigen.
