Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Nonstick cookware, such as frypans and saucepans, has been coated with a material called polytetrafluoroethylene (PTFE), commonly known as Teflon.
Teflon is a synthetic chemical made up of carbon and fluorine atoms.

Teflon is polytetrafloroethylene $- (F_{2} C - C F_{2})_{n} -$ .

It is chain growth homopolymer of tetrafluoroethylene $(F_{2} C = C F_{2})$ .

The nonstick surface makes Teflon-coated cookware convenient to use and easy to clean.
