- AWool
- BSilk
- CRubber
- ✓$\text{PVC}$
✓
Answer
Correct option: D.
$\text{PVC}$
There are two types of polymers: synthetic and natural.
Synthetic polymers are derived from petroleum oil and made by scientists and engineers.
Examples of synthetic polymers include nylon, polyethene, polyester, Teflon, and epoxy.
Polyvinyl chloride, commonly abbreviated $\text{PVC},$ is the third$-$most widely produced synthetic plastic polymer.
Natural polymers occur in nature and can be extracted. Examples of naturally occurring polymers are silk, wool$, \text{DNA},$ cellulose and proteins and rubber.
