Detailed Solution

The above statement is true.
Silk is a fine, strong, silky, and gleaming fibre created by silkworms when they spin cocoons. Silk is a natural fibre derived from the silk moth, an insect. Silk is thus an animal fibre. The silk fibre is composed of a protein. The silk yarn appears delicate yet as robust as a corresponding steel thread. In addition, silk fibres are luxuriously soft.
