Airway obstruction contributing to increased airflow resistance and hypoventilation in asthma is caused by:
A) type II alveolar cell injury and decreased surfactant.
B) alveolar fibrosis and pulmonary edema.
C) mucous secretion, bronchoconstriction, and airway edema.
D) collapse of the cartilaginous rings in the bronchi.
