A) Infection
B) Coagulation
C) Inflammation
D) Perfusion
C) Inflammation
Explanation: A) Asthma is a condition of reactive airway constriction, in which parts of the respiratory tract are sensitive to allergens. In the presence of an environmental allergen, parts of the respiratory tract constrict, restricting the flow of air into the lung. The reduction in air flow leads to decreases in the concentration of oxygen in the bloodstream. The allergen stimulates the immune system, which releases inflammatory mediators. The resulting inflammation contributes to the reduction of airflow.
