Answer: Option D) Peptide bonds are amide linkages.

Explanation:

A peptide bond is formed between two amino acids with the loss of one molecule of water and the formation of an amide (CO-NH2) bond.

Usually the carboxyl group (COOH) of the first amino acid links with the amino group (NH2) with the loss of H2O, thus forming an amide linkage

Answer: The options are not complete and the given options are wrong.

Option E. Tripeptide contain three amino acids residue is the correct answer.

Explanation:

Peptide bond are covalent chemical bond that link two molecules which are formed when one molecule of carboxyl group react with one molecule of amino group releasing a molecule of water. It is a condensation reaction and take place between amino acids. A tripeptide contain three amino acids residue with three peptide bond.
