Monomers link to form molecules called polymers. a limitless number of polymers can be built from monomers. which statement best explains how such a large number and variety of polymers can be built from monomers?

a. there are a limitless number of monomers that can combine to form polymers.
b. each time a monomer links with another monomer, a new type of polymer is formed that is unlike any previously formed.
c. each new polymer has one more monomer linked to it than polymers formed previously; therefore, an infinite number of polymers form.
d. a small set of monomers can come together in a wide variety of ways, forming limitless types of polymers.
