Final Answer :
C
Explanation :
The one letter symbol for tryptophan is W, which is not an option in the answer choices. However, a unique feature of tryptophan is that its side chain can absorb UV light, making it useful for certain spectrophotometric analyses. Therefore, the answer must be C, which is the only option that contains a UV light-absorbing aromatic amino acid: phenylalanine (F).
