Correct Answer: Cocoon of silk worm
Solution : The correct option is - Cocoon of silk worm
The larvae of the mulberry silkworm form cocoons from which silk is produced. An organic protein fiber that can be woven into some types of textiles is silk. Certain insect larvae synthesize fibroin, the major component of the protein fiber that makes up silk. Due to the triangular prism-like structure of the silk fiber, which enables silk cloth to refract incoming light at different angles, producing changing colors, silk has a shimmering effect.
