Base your answer on the chemical equation shown in the diagram below and on your knowledge of biology. Amino groups are found in molecules of:

A, only
A and B, only
A, B, and C, only
A, B, C, and D

The correct option is;

A, B, and C, only

Explanation:

The amino group is the functional group of the form CH-NH₂ consisting of single bonds formed between hydrogen atoms, aryl groups, alkyl groups or two or more of such groups combined together bonded with a nitrogen atom. An amine is an organic compound that has an amino group in its composition or structure

Therefore, the amino group can be found in the molecules of A, B, and C only.
