AGC TTT CG

Reason: The original sequence is 9 bases (AGC TTA TCG). AGC TTT CG has 8 bases (one base deleted), which is not a multiple of three and therefore causes a frameshift. The other choices remove or change whole codons (multiples of three) or substitute a base, so they do not produce a frameshift.
