Accepted Answer

A compound composed of two or more amino acids is a peptide. Choice B (Amino) refers to a single amino acid, and choice C (Nucleotide) refers to the building blocks of nucleic acids, not proteins. Choice D (Peptide and Amino) is incorrect because peptides are composed of amino acids, so this choice is redundant. Choice E (All of these) is incorrect because nucleotides are not involved in the formation of peptides.
