"CF is more common in females than males."

"Being of African descent significantly increases the risk of developing CF."

Answer and Explanation

The Correct Answer is C

A) Incorrect. CF occurs at a similar frequency in both males and females.

B) Incorrect. CF is not significantly associated with any specific ethnicity, and the risk is not influenced by being of African descent.

C) Correct. A family history of CF increases the risk because CF is an autosomal recessive genetic disorder, and having affected family members increases the likelihood of carrying CF gene mutations.
