Which of the following is a semi synthetic polymer Silk Wood rayon natural rubber?

The correct answer is Silk. Silk is a natural polymer. Natural polymers occur in nature and can be extracted. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins, and rubber.

Why is rayon semi synthetic?

Rayon was the first artificial (man-made) fibre. It is a manufactured from cellulose fibre. It is produced from naturally occurring polymers it is neither a truly synthetic fibre nor natural fiber. Thus it is a semi synthetic fiber.
