D Correct answer
Explanation

Aromatic amino acids can be detected by Xanthoproteic reaction. Edman’s reaction can be used to determine the amino acid sequence of a protein. Millon’s test is for identification of L-2-Amino-3-(4-hydroxyphenyl)propanoic acid. Hopkins-Cole test is for identification of 2-Amino-3-(1H-indol-3-yl)propanoic acid.
