Correct Answer is B

Explanation

A) Incorrect. CF primarily affects the lower respiratory tract, particularly the bronchi and bronchioles, rather than the upper respiratory tract.

B) Correct. CF leads to thickened mucus in the airways, which can cause inflammation, recurrent infections, and progressive lung damage.

C) Incorrect. Enlarged tonsils and adenoids are not a typical manifestation of CF-related respiratory complications.

D) Incorrect. CF affects both the bronchial tubes and the entire respiratory system, often leading to chronic lung infections.

A. "CF results from a dominant genetic mutation inherited from one parent." B. "CF occurs due to the presence of two dominant genetic mutations." C. "CF is caused by a recessive genetic mutation inherited from both parents." D. "CF is a non-genetic condition caused by environmental factors."

Correct Answer is C

Explanation

A) Incorrect. CF is an autosomal recessive genetic disorder, meaning that both copies of the CFTR gene must carry a mutation for the condition to manifest.

B) Incorrect. CF is not caused by dominant genetic mutations.

C) Correct. CF results from inheriting two recessive genetic mutations, one from each parent, leading to defective CFTR protein function.

D) Incorrect. CF is primarily a genetic disorder with well-established genetic mutations associated with its development.
