The correct answer is - C-terminal

Explanation:

Polypeptide chains are nothing but the linked amino acid sequences together which is takes place with the help of mRNA, ribosome, and tRNA in a living cell or organism. Polypeptide chain has two ends with two functional groups a carboxyl group end and an amino group end of the polypeptide chain.

The next amino acid added to the carboxyl group end of the polypeptide chain with the bond known as peptide bond and the reaction known as a condensation reaction and a molecule of water is released.
