Which amino acid is explicitly mentioned as being coded by CCC and CCT?

Explanation:
Three-nucleotide codons in mRNA specify amino acids. The codons CCC and CCT both code for the amino acid proline. None of the options list proline, whose codons are CCC and CCT. For reference, glycine is coded by GGU/GGC/GGA/GGG; alanine by GCU/GCC/GCA/GCG; leucine by UUA/UUG/CUU/CUC/CUA/CUG; valine by GUU/GUC/GUA/GUG.
