Based on the description of monomers and polymers, monomers are the basic building blocks that join together to form polymers, which are larger, more complex structures.
If you are looking to classify A, B, and C based on whether they represent monomers or polymers, the correct response would be the one that accurately identifies which elements are the individual monomers (B) and which are the larger structures (A and C).
From the options listed, if A and C are indeed more complex structures compared to B, which is a single unit, then the correct answer would be:
A and C are like polymers and B is like a monomer.
This option indicates that A and C are formed from multiple units, making them polymers, while B is a single unit, making it a monomer.
