Answer:
B) A small molecule that can chemically bond with other monomers to form a polymer
Explanation:
A monomer is the term which refers to a small molecule that has the capability to from a covalent bond with other like molecules to produce a polymer. These monomers have functional groups that undergo a chemical change when making polymers, a process where monomers are connected in a stepwise manner to build long chains and/or cross linked networks. In other words, each type of polymer depends on the kind of monomer being used and the kind of bonding that occurs giving rise to properties of polymer material that would be fit for one use or the other.
Therefore, the correct answer choice is B).
