Answer 1

Hint: A polymer is a substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.

Complete step by step answer:
We have been provided with polymers: polystyrene, glyptal, polyvinyl chloride, Bakelite
So, first polymer is polystyrene,
Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight.
So, polystyrene is used for manufacture of toys.
Next, we have glyptal,
This is a polymer of ethylene glycol and phthalic acid. They are also called alkyd resins. Glyptal is used as binding material, cement etc.
So, glyptal is used in paints and lacquers.
Next polymer is polyvinyl chloride,
Polyvinyl chloride (PVC) is the world's third - most widely produced synthetic plastic polymer. About 40 million tons of PVC are produced each year. PVC comes in two basic forms: rigid and flexible
So, polyvinyl chloride is used in raincoats,
Last, we have Bakelite,
 Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde.
So, Bakelite is used in computer discs.
Therefore, we can conclude that option (C) is correct.

Note: Polymer properties depend on the chemicals that the polymer is made from and polymerization conditions that ultimately set molecular architecture: chemical linkage type, chain length, and the nature of the end groups. The type of the monomer - repeat unit that forms a polymer has a strong effect on polymer properties.
