The DNA segment has a base order CCC ATA GCT.
A deletion in the first codon triplet would result in the removal of one base from the segment.
Looking at the given options:
A) CCA TAA CT: This does not exhibit a deletion.
B) CCA ATA GCT: This does not exhibit a deletion.
C) CCC TAG CT: This exhibits a deletion, as the first codon triplet "CCC" is missing.
D) CCA TAG CT: This does not exhibit a deletion.
Therefore, the correct answer is option C) CCC TAG CT, as it exhibits a deletion in the first codon triplet.
