Explanation / Answer

Correct answer:- (c) a non polar amino acid is substituted by another non polar amino acid

Explanation:- CF is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). The most common mutation, F508, is a deletion ( signifying deletion) of three nucleotides that results in a loss of the amino acid phenylalanine (F) at the 508th position on the protein.
