(D) The Biuret test is a chemical test used for detecting the presence of peptide bonds.It gives a positive result for compounds containing at least two peptide linkages $(-CO-NH-)$.$1$. Glycine: An amino acid,contains no peptide linkage.$2$. Glycylalanine: $A$ dipeptide,contains only one peptide linkage.$3$. Tripeptide: Contains two peptide linkages.$4$. Biuret: Contains two peptide linkages $(NH_2-CO-NH-CO-NH_2)$.Therefore,only the Tripeptide and Biuret give a positive Biuret test.The total count is $2$.
