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.
