Best answer
Correct answer is (c) Chlorinated PVC

The best explanation: Polyvinyl chloride (PVC) is a polymer made by the polymerization of monomer vinyl chloride. They are low-cost polymers which have good resistance to chemical, oil, electrical attacks. The common forms of PVC are plasticized PVC (PPVC), un-plasticized PVC (UPVC), chlorinated PVC (CPVC), and polyvinylidene chloride (PVDC).
