Firstly, the image itself is totally different from that of the options. None of the options actually fit the image. So, either there should be a "None of these" option or there should be a different image in which at least one option fits. I ask SOF to kindly make the needed changes.

reechik ghosh from dps, farakka

from ,
Class :
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:

Ashwak from Cambridge, Jalandhar
Class : Class 9
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 7:

from ,
Class :
as larva produces and when it is fully produced it forms a cocoon

Ans 8:

Aayush Reddy Bomidika from Delhi Public School Nacharam, Hyderabad
Class : Class 9

Ans 9:

from ,
Class :
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 10:

from ,
Class :
I thought the silk is obtained from the cocoon

Ans 11:

Ryan Ganguly from Ebenezer International School, Bangalore
Class : Class 8
The answer is C as at that time of a Silkworms life it will produce silk. With that silk they will make a cacoon and then they will become a Moth. While it is a Pupa it does not have the ability to make Silk hence the answer is C

Ans 12:

from ,
Class :
no it is c

Ans 13:

from ,
Class :
it must be c . at cocoon stage silk is already produced

Ans 14:

from ,
Class :
ans:c,you may think d,but only in larval stage it produce silk in option d it is in a cocoon stage it cannot produce silk

Ans 15:

from ,
Class :
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 16:

Hritvi from Podar International School, Mumbai
Class : Class 8
OPTION C

Ans 17:

AARAV AGRAWAL from BIRLA DIVYA JYOTI, SILIGURI
Class : Class 8
This is a trick question.. It says 'produced', not 'obtained'.. The larvae produce the silk fibre, then it is obtained from cocoon..

Ans 18:

ARUNAV from DPS VINDHYANAGAR, VINDHYANAGAR
Class : Class 10
really confusing ... the answer option d is correct in the sense that produces means extracting the silk or when it is ready to extracted by humans. but option c is correct when produces means that when larva , itself after the fourth moult stage produces silk.

Ans 19:

Bhumi Chheda from SVKM J V Parekh International School, Mumbai
Class : Class 9
it is c because the silk has already started getting produces when it is larva

Ans 20:

Ronav Kerkar from Jamnabai Narsee School, Mumbai
Class : Class 7
admin please answer

Ans 21:

Parth Gupta from Presidium Gurgaon, Gurgaon
Class : Class 8
answer is c because in the pupa stage the silk is already produced and in the larvae stage it produces silk when it is ready to go in the next stage of its life
