Answer: The correct answer is -

(C.) A-G-T-G-G-A-T.

Substitution is a type of point mutation (a permanent change in the nucleotide sequence of DNA when one nucleotide base sequence is substituted by another base).

In this question, Cytosine (C) at second position is substituted by Guanine (G) only in option C).

Thus, option C) is the right answer.
