This polymer must D. be made of large molecules with repeating units.

A polymer consists of long chains of smaller repeating units called monomers.

For example, polyethylene consists of long chains of ethylene (CH₂=CH₂) units joined together end to end.

The formula for polyethylene is -CH₂CH₂-(CH₂CH₂)ₙ-CH₂CH₂-, where n is usually a number between 500 and 10 000.


The correct answer is D
