Hint:Polymer is a substance consisting of many repeating units called monomers. Polymers can be synthetic, natural as well as semi-synthetic. Polymers have a large molecular mass. The polymer used consists of fluorine and ethylene.

Complete answer:
SBR is styrene-butadiene rubber and it is included in the group of synthetic rubbers. SBR has the monomers, styrene and butadiene. It is a commodity material. It is largely used in pneumatic tires. SBR has good abrasion resistance and also its stability is more. From using various types of SBR, about 50 percent of car tires are made.
PAN is also known as polyacrylonitrile. It is thermoplastic yet it does not melt under normal conditions. The main monomer is acrylonitrile. It has a variety of uses which includes ultrafiltration membrane, fibres for textile, oxidized PAN fibres, etc. It has high tensile strength.
PTFE is also known as polytetrafluoroethylene. It has numerous applications and is a synthetic fluoropolymer of tetrafluoroethylene. Its common is Teflon. The major applications of PTFE include insulation of wiring. Teflon is also used as aerosol lubricant and as musical instrument lubrication product. It is also best known for its use in coating non-stick frying pans and other cookware.
PVC is also known as polyvinyl chloride. It is a synthetic plastic polymer and the third most widely used product. The main use of PVC is in producing pipes for municipal applications.
PTFE is the polymer which can be beneficial for lubrication. It is also used as an insulator.

Therefore, the correct option is C.

The term polymer is derived from the Greek words ‘polus’ meaning many and ‘meros’ meaning part. Polymers are synthesized by a combination of repeating units called monomers.
