Which of the following pairs accurately connects a macromolecule to its monomer?
a. carbohydrates–amino acids
b. nucleic acids–nucleotides
c. proteins–nitrogenous bases
d. lipids–phosphate groups

A monomer can be defined as the molecule that is capable of binding in long chains. The monomers bind together to form different polymers by the process of polymerization.

The monomer of carbohydrate is monosacchride. The monomer of proteins is amino acid, and that of lipids is glycerol and fatty acids. These three macromolecules are wrongly paired in the question.

The monomer of nucleic acids is nucleotide. This is correctly matched.

Hence, the correct answer is 'Option B - nucleic acids - nucleotides'.
