Which best explains the difference between a monomer and a polymer?
a monomer is larger than a polymer.
a monomer contains carbon and a polymer does not.
a polymer contains carbon and a monomer does not.
a polymer is larger than a monomer.

A polymer is larger than a monomer.

Explanation: A polymer is formed by the repeated addition of small units called as monomers. Thus a polymer is always larger than a monomer.

If a monomer contains carbon, the polymer would also contain carbon as combination of monomers produce polymers. For example:

       ethene                           polythene

Small molecules of ethene polymerizes to form a large molecule polythene.
