Best answer
Right answer is (d) Carboxypeptidase

Best explanation: Exopeptidases catalyze the hydrolysis of a peptide bond from the ends. Carboxypeptidase is an exopeptidase. Whereas trypsin, chymotrypsin, and elastase are examples of endopeptidases. Endopeptidases hydrolyze the peptide bonds between specific aminoacid.
