A.
The passage states that cystic fibrosis is caused by a mutation in a gene and leads to disease symptoms, so genetic mutations can contribute to or cause diseases in humans. The other choices are false: mutations do not always cause death, are not limited to plants/wild animals, and do not usually cause excess mucus (that is specific to cystic fibrosis).
