This question can be answered using a codon table/chart.
We know that a codon is made up of 3 nucleotides, each specifying a certain amino acid. The first sequence reads:
**Note that it is important to make sure that you are looking at the correct reading frame**
AUG AUA GUG UAC
Met (start) - Ile - Val - Tyr
This sequence has 4 amino acids.
The second sequence reads:
AUG AUA GUG UAG
Met (start)- Ile - Val - Stop
This sequence has 3 amino acids due to the Stop codon halting translation.
Therefore, the first has one more amino acid than the second, and your answer will be C.
