Answer:
Cystic fibrosis (CF) is a genetic (inherited) disease that causes sticky, thick mucus to build up in organs, including the lungs and the digestive system. In people who have CF, thick mucus clogs the airways and makes it difficult to breathe.

The answer is A. Sex-linked traits are more often expressed in males because they are typically carried by the X chromosome and they are also typically recessive. Males only inherit one X chromosome, so if the one they inherit is linked to the disease, they will express it no matter what. Females, on the other hand, can be carriers if they inherit one X chromosome with the disease. This is because their other X chromosome can be normal, which would dominate the expression of the disease on their other X chromosome.
