Since, the original DNA sequence has not been provided, the mutation can be an insertion/deletion or a frameshift mutation.

Explanation:

Frameshift Mutation:

A frameshift mutation is the alteration in the reading frame of the DNA due to the addition/deletion of one or two nucleotides.This type of mutation moves the mRNA sequence one or two bases forwards or backwards which disrupts the three base codons sequence required for translation into proteins.The CT at the end of the sequence is indicative of a frameshift in the DNA reading frame.Frameshift mutation affect all amino acids in a polypeptide chain as all codons are moved one or two steps forwards or backwards.

This is giving me a headache i have asked others and they don’t know it either

Ithink the answer is d.
