Answer:

B. The R group.

Explanation:

All amino acids have an amino group, a central carbon and hydrogen atoms.

What differentiates some amino acid molecules from others is the additional carbon chain attached to the central carbon.

In organic chemistry, these chains are also expressed with the letter "R".
