The monomers are nucleotides for: a-proteins b-lipids c-carbohydrates d-nucleic acids

The Option D is correct.

All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers "nucleotides."

The nucleic acids are the building blocks of living organisms.

Nucleic acid is a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria .
