Solution

The correct option is C Peptide bond
Proteins are polymers of amino acids. Amino acids are joined by peptide bonds forming polypeptide strands.
Two amino acids linked by one peptide bond is called a dipeptide. In this, the amide is formed between -COOH and NH2 group by the elimination of a water molecule.
Thus, the correct answer is option C.
