The Correct Answer is B

A) Incorrect. Wheezing and chest pain can occur in CF, but a chronic cough with thick mucus production is often one of the earliest respiratory symptoms.

B) Correct. A chronic cough with thick, sticky mucus is a hallmark symptom of CF due to the accumulation of mucus in the respiratory tract.
