Most macromolecules are also  atoms binding together.  Polymers are made up of  numerous monomers.

(Correct option atoms - monomers)

Explanation:

Atoms are the structural unit of matter, with chemical properties that allow their interaction with other atoms to create molecules.  An example of this is common salt, a molecule that is formed by the union of sodium and chlorine.

A monomer is a molecule, such as glucose (C₆H₁₂O₆), which when joined to other monomers of the same type can form a polymer. An example of this is cellulose, a biological polymer formed by multiple β-glucose units.
