A frameshift mutation occurs when a nucleotide is either inserted or deleted, which changes the reading frame of the codons. Option C shows a frameshift mutation because several letters have been deleted, causing a shift in the reading frame of the sentence. This completely changes the meaning of the sentence. Option A is the original sentence and represents the wild-type or normal sequence, option B is a point mutation, and option D is a substitution mutation. None of them represent frameshift mutations.
