During protein synthesis, the peptide bond between amino acids is formed by the process of see section 3.1 ( page 80) .

The peptide bond is the link between two amino acids, which is formed by the reaction between the carboxylic group and amino group of two different molecules of amino acids.

The reaction between the carboxylic group an amino group result in the loss of water molecule. This kind of reaction is known as condensation reaction. It is also referred as dehydration reaction.

substitution is the answer in this case

option c is the correct answer.
