Solution

The correct option is A True
Silk fibre is obtained from the cocoon of the silk worm. During the processing of silk, the cocoons are boiled to kill the larvae before it comes out from the cocoon.

Once the larvae comes out of the cocoon, we won't be able to get a continuous thread of silk from the cocoon.
