Answer 1

Option B is correct

Step-by-step explanation:

Cystic fibrosis which is also known as CF, mucovoidosis, or mucoviscidosis is caused by a defective gene which causes the lungs and the digestive system to become clogged with sticky mucus resulting the inflammation of the lungs thereby causing difficulty in breathing.

Cystic fibrosis is a genetic condition. Cystic fibrosis can't be caught or developed; it can only be caused by inheriting two copies of the faulty gene.
