C- Protein

Explanation:

Peptide bond -

The bond between the carbonyl group and the the amine group , is referred to as peptide bond .

Peptide bond is written as -

--CONH --

From the molecules given in the question , protein molecule has peptide bond .

Since ,

protein molecules are composed of amino acid chains via some force of interactions ,

And , since , amino acid have a peptide bond .
