The Correct Answer is A
Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, which is inherited in an autosomal recessive manner. This means that a child must inherit two copies of the mutated gene (one from each parent) to develop the disorder. If only one parent carries a copy of the mutated gene, their children will not develop cystic fibrosis but may be carriers of the gene.
