Question

Silk fibre is drawn from the cocoon of _________.

• A. butterfly
• B. worm
• C. silkworm
• D. both $A$ and $B$

Answer 1

Answer: (C)

Silkworm, its larvae are fed with mulberry leaves, and, after the fourth moult, they climb a twig placed near them and spin their silken cocoons.

This process is achieved by the worm through a dense fluid secreted from its structural glands, resulting in the fibre of the cocoon.

Hence the option C is correct.
