Answer 2

PVC, Polythene, Bakelite (option 4) is the group contains all synthetic substances.

The first synthetic thermoplastic polymer to be successful commercially was nylon. For synthetic fibres, use polyester, polyethylene terephthalate, or terylene. The synthetic fibre kevlar, which is frequently used in body armour, and wool together were lighter, more affordable, and more effective in humid environments. Cotton is a soft, fluffy staple fibre that develops around the seeds of cotton plants in a boll, or protective capsule.

PVC, Polythene, and Bakelite are all examples of synthetic polymers, but Rayon is made from natural cellulose and cannot be categorised in the same category.
