Correct Answer is A
Explanation
A. It is difficult to keep the alveoli open- surfactant reduces alveolar surface tension; without it, alveoli collapse (atelectasis).
B. Bronchioles relax- not directly related to surfactant.
C. The alveoli fill with water- surfactant prevents collapse, not water entry.
D. Air enters the intrapleural space- this would cause a pneumothorax, unrelated to surfactant function.
