The correct answer is: C.Monomers

Explanation:

All macromolecules (such as proteins, nucleic acids, and polysaccharides) are made up of smaller subunits called monomers. These monomers bond together to form larger structures known as polymers.

For example:

1.Proteins are made up of amino acids (monomers).

2.Nucleic acids (like DNA and RNA) are made up of nucleotides (monomers).

3.Polysaccharides (like st...
