Solution

The correct option is A (i)-(d), (ii)-(f), (iii)-(a), (iv)-(b), (v)-(c), (vi)-(e)
Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyester fabrics can provide specific advantages over natural fabrics, such as improved wrinkle resistance, durability and high color retention.

Polytetrafluoroethylene or Teflon or PTFE is used as a non-stick coating for pans and other cookware. It is very non-reactive, partly because of the strength of carbon–fluorine bonds and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear and energy consumption of machinery.

Rayon is a man-made redeveloped cellulose fiber. Rayon is produced from naturally occurring polymers like wood pulp

Nylon : It is used for making parachutes and stockings

Bakelite : It is used for making Electrical switches

Melamine : It is used for making fire-resistant clothes

Option A is ocrrect.
