• (A) 1-a, 2-d, 3-b, 4-c
• (B) 1-d, 2-a, 3-b, 4-c
• (C) 1-d, 2-a, 3-c, 4-b

Answer 1

The Correct Option is B

Explanation:
Rayon:Rayon is a synthetic fibre whose properties are similar to that of silk.Rayon is obtained from a natural source like wood pulp.It has a very shiny appearance and hence called artificial silk.​Teflon:Teflon is short for tetrafluoroethylene, also known as PTFE.It is used to make non-stick cookware, pans because it is unreactive in nature and has non-stick properties.It is a synthetic polymer.Bakelite:Plastic is also a polymer like synthetic fibre.There are two types of plastics: thermoplastics and thermosetting plastics.Thermosetting plastics are the one which when moulded once cannot be softened by heating.PVC:PVC stands for Poly Vinyl Chloride.It is a plastic that gets deformed easily when heated and can be moulded again into other forms.It is used to make pipes, containers, various type of toys etc.Column A (FIbres)Column B (Uses)1. Rayond. Clothes2. Teflona. Coating of non-stick3. Bakeliteb. Handles and Switches4. PVCc. PipesThe correct option is thus 1-d, 2-a, 3-b, 4-c.Hence, the correct option is (B).
