Answer

Brief Explanations:

A substitution mutation occurs when one nucleotide is replaced by another. In the given sequence, the 'G' in the 6th position of the original sequence "GCTTAGCGC" is replaced by 'T' in the mutated sequence "GCTTATAGCGC". Duplication involves adding extra copies of a segment, inversion is reversing a segment, and translocation is moving a segment to a non - homologous chromosome.

Answer:

C. substitution
