C) Incorrect. Pulmonary function tests assess lung function but do not confirm CF by analyzing genetic mutations.

D) Correct. Genetic testing is a diagnostic procedure commonly used to confirm CF by analyzing the specific CF gene mutations present in an individual.

A. "CF is caused by a dominant genetic mutation that always manifests in affected individuals." B. "CF results from the presence of two recessive genetic mutations, one inherited from each parent." C. "CF is due to a spontaneous genetic mutation that occurs during a person's lifetime." D. "CF is exclusively caused by environmental factors and is not related to genetics."
