the answer is d only in the cocoon stage they are heated in the hot water so that the reproducing caterpillar will die and it will be very easy to extract silk fiber from it.

Ans 2:

Mradul from Modern public school bhiwadi, Bhiwadi
Class : Class 7
IT IS 'D' BECAUSE AT COCOON STAGE THE CATERPILLAR PRODUCES SILK FIBRES AND KNOTS AROUND IT AND COVERS HIMSELF.AFTER SOME TIME THE SILK FIBRES GETS HARDEN DUE TO THE GUMMY SUBSTANCE WHICH THE CATERPILLAR PRODUCES............IT IS CALLED "FIBROIN" WHICH IS MADE UP OF PROTEINS.ON HEATING THE COCOONS IN WATER THE SILK AGAIN BECOMES SOFT AND IS EXTRACTED FROM COCOONS........THIS PROCESS IS CALLED "REELING OF SILK"

Ans 6:

No, the answer is 'C' only. In pupa stage the silk fiber is only obtained, but actually it is produced by larva and in question it is asked which stage produces fiber. Hence, the answer is 'C".

Ans 7:

Parth Gupta from Presidium Gurgaon, Gurgaon

Answer should be C ,as only larvae in the life cycle of moth produce silk fibres , pupa or cocoon does NOT make silk fibres . They only undergo change in stage IN the silk fibres. They do not have the ability to produce silk fibres !

Ans 14:

Ryan Ganguly from Ebenezer International School, Bangalore
