Verified by Experts

The correct Answer is:
B, C

Option (A) : Incorrect, Natural number is a linear polymer of isoprenen (2-methyl -1,3-butadiene) also known, as cis-1,4-poly isoprene.
Option (B): Correct, Nylon -6 contains only one kind of monomeric unit called caprolactam.
Option C: Correct Tetrafluoroethene (TFE) is heated with a free radial peroxide or ammonia persulphate catalyst at high pressure to given polytetrafluoroethene (PTFE).
