Answer 2

Answer:

Silk is not a synthetic fiber.

Option D

Explanation:

Synthetic fibres are usually made from the polymerization of organic chemicals in high heat followed by cooling to room temperature resulting in formation of textile fibres. Silk is made from the silkworm.

Silkworm spins a cocoon of thread around itself. It is used for the protection of silkworms. Now the silkworm grows inside the cocoon to form a pupa. Now silk thread is collected from the cocoon and it is made into a thread.
