A 22-year-old man is brought to the emergency department in respiratory distress 15 minutes after he was stung on the arm by a wasp. His pulse is 100/min, respirations are 30/min, and blood pressure is 100/60 mm Hg. Physical examination shows grunting respirations and subcostal retractions. Expiratory wheezes are heard over both lung fields. There is generalized urticaria. Secretion of the molecule causing this patient's symptoms is most likely mediated by which of the following? (A) Activation of complement (B) Activation of mast cell (C) Activation of T lymphocytes (D) Production of IgA (E) Production of IgG (F) Production of IgM
