Which of the following pairs accurately connects a macromolecule to its monomer?

A. Lipids - phosphate groups

B. Nucleic acids - nucleotides

C. Carbohydrates - amino acids

D. Proteins - nitrogenous bases

I think it's B - Nucleic acids~Nucleotides

The correct answer is B. Nucleic acids - nucleotides. That is because nucleic acids such as Ribonucleic acid and deoxyribonucleic acid are both made out of nucleotides which is a type of molecules that build into them. There are four in each, but the two types use 3 of the same ones and a different one.
