Polymer vs. Macromolecule: What's the Difference?

[mcconnellalex01]

Homework Statement

I was asked which of these is NOT a polymer and I'm not sure how to answer it.
A.) Camp-Stove fuel
B.) Polyester
C.) DNA
D.) Starch
E.) Plastic

Relevant Equations

A polymer is a useful chemical made of many repeating units
A macromolecule is a chain of many different units

I am aware that there is a difference between a polymer and a macromolecule (due to types of bonds, structure, etc.) but all of these seem to be chains like polymers to me. I know that is incorrect because there is no option for all of the above.

Maybe if you consider in more detail what each of the possible answers is made of.

Hi McC:

Here is a hint. The key word is "many".
