Which statement defines a polymer?

Which statement defines a polymer?

• A. A long chain molecule formed from joining many small molecules (called monomers)
• B. A single atom
• C. A simple compound
• D. A solution of many molecules

Answer: (A)

Polymers are very large molecules formed when many small units called monomers join together in a chain. This statement is correct because it describes a long chain made from many monomer units linked together, which is exactly how polymers are built. A single atom isn’t a polymer, a simple compound is just a small molecule, and a solution of many molecules describes a mixture rather than one large chain molecule.
