Best answer
The correct choice is (b) 4

Easiest explanation: The life history of silk moth passes through four stages-egg, larva, pupa and adult. About 50% of the cocoon are kept in boiling water to kill pupa and then thread is reeled off. Rest 50% are kept as such so that they become adult and the life cycle starts once again.
