Ans: A
Feedback:
Extrinsic or atopic asthma is typically initiated by a type I hypersensitivity reaction induced by exposure to an extrinsic antigen or allergen such as pet dander. Intrinsic or nonatopic asthma triggers include respiratory tract infections, exercise, hyperventilation, cold air, drugs and chemicals, hormonal changes and emotional upsets, airborne pollutants, and gastroesophageal reflux.
