Correct answer: They are made of repeating subunits.
Why:
- A polymer, by definition, is a large molecule built from repeating monomer units.
- "They share ionic carbon bonds." is wrong — carbon–carbon and carbon–heteroatom bonds in polymers are covalent; polymers can have ionic groups but not ionic carbon bonds.
- "They are at least 100 monomers long." is false — polymer chain length varies widely; there is no strict 100‑monomer cutoff.
- "They come from living things." is false — some polymers are natural (proteins, cellulose), but many are synthetic (plastics).
