Solution

The correct option is C d
  • Each amino acid consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), to an R group that varies in each amino acid, and to a hydrogen atom.
  • Basic amino acids have an extra basic (amine group) in the substituent (R) group as in figure D given in the question.

So, the correct option is (B).
