A Correct answer
Explanation

Mylar is the brand name of polyethylene terephthalate (PETP). Poly ethylene oxide (PEO) is formed from the polymerisation of ethylene oxide. The preparation of PEO is sold under the brand names GoLYTELY, GaviLyte C, NuLytely, GlycoLax, Fortrans etc. Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The most common brand or trade name of PTFE is Teflon. Poly-p-phenylene-2,6-benzobisoxazole (PBO) has very high tensile strength and thermal stability. It is marketed as zylon and is used in the making of tennis racquets, table tennis blades, body armor etc. Hence, the representation of codes A - 2, B - 1, C - 4, D - 3 is correct.
