Process of separation of silk from cocoon is called?

Correct option is D

The process of separating silk from the cocoon is called "Reeling." During reeling, the silk threads are carefully unwound from the cocoon, typically done by placing the cocoon in hot water to soften the sericin (a protein binding the silk threads). The softened silk fibers are then gently unraveled, forming a continuous thread that can be further processed into silk fabric.
