A Correct answer
Explanation

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The best known brand name of PTFE is Teflon. Polyvinylidene difluoride (PVDF) is a highly non-reactive and pure thermoplastic fluoropolymer produced by the polymerisation of vinylidene difluoride. PVDF is sold under a variety of brand names including Hylar (Solvay), Kynar (Arkema) and Solef (Solvay). Poly ethylene oxide (PEO) is form from the polymerisation of ethylene oxide. The preparation of PEO is sold under the brand names Golytely, Gavilyte C, Nulytely, Glycolax, Fortrans, etc. Mylar is the brand name of polyethylene terephthalate (PETP). Hence, the representation of codes A-2, B-1, C-4, D-3 is correct.
