The correct answer is OPTION D: Phenolic resins.
- A thermoset is a type of polymer that is strengthened permanently by curing a soft solid or viscous liquid prepolymer or resin.
- Curing is done with heat or suitable radiation, and it can be hastened using high pressure or a catalyst.
- Phenolic resins are examples of thermosetting polymers, whereas thermoplastic polymers soften repeatedly when heated.
