Correct Answer is B

Explanation

A. More than 250 mL of air moves in and out of the lungs with each breath: This describes tidal volume but does not directly stimulate the cough mechanism.
B. Foreign substances are propelled by the cilia toward the respiratory tract: Irritation by foreign particles stimulates the cough reflex to clear the airways.
C. Dehumidified air enters the upper airway passages: Dry air can cause airway irritation but does not consistently trigger a cough reflex.
D. The blood transports carbon dioxide to the lungs: This describes gas exchange, which does not directly relate to triggering the cough mechanism.
