D Correct answer
Explanation

This option is correct because all are correctly matched. Aromatic amino acids can be detected by xanthoproteic reaction. Edman degradation can be used to determine the amino acid sequence of a protein. Millon’s test is used for identification of tyrosine. Hopkins-Cole reaction is used for identification of tryptophan.
