Correct Answer: D

Rationale: The correct answer is D: Chest physiotherapy, with postural drainage, percussion, and vibration. This approach helps loosen and clear mucus from the lungs, improving pulmonary function in cystic fibrosis. Postural drainage helps drain mucus from specific lung segments, percussion loosens mucus, and vibration further helps dislodge it. This therapy is essential in preventing lung infections and maintaining lung function.

A: Corticosteroids are not typically used to promote pulmonary function in cystic fibrosis, as they may have limited effectiveness in managing mucus clearance.
B: Continuous low-flow oxygen may be used in some cases, but it does not directly target mucus clearance or improve pulmonary function.
C: While antibiotics are important in managing infections in cystic fibrosis, they do not directly address mucus clearance or promote pulmonary function effectively.
