c. an organic compound that contains multiple side chains
d. an organic compound that is a carbohydrate

Hey there,

Your answer is D).  an organic compound that is a carbohydrate

Definition: a simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.

Amino acids are organic compounds containing amine and carboxyl functional groups, along with a side chain specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, although other elements are found in the side chains of certain amino acids.
