It should be D. Because nylon would never once burn with smell of paper in it's entire career. SOF, you gotta chnage the answer man.

Ans 4:

Class : Class 9
nylon burns with a smell of plastic, not burning hair. WTF?

Ans 5:

Class : Class 8
Nylon does not have the smell of burning hair. So the answer should be d.

Ans 6:

Class : Class 9
wrong answerthe answer should be B

Ans 7:

Class : Class 9
yes the answer is D. nylon burns with a smell of celery because its a synthetic fibre.

Ans 8:

Class : Class 9
IT must be D! Nylon does not burn with the smell of burning hair as it is purely synthetic and has no relation to the protein based hair.

Ans 9:

Class : Class 8
wool burns with smell of burning hair

Ans 10:

Class : Class 9
How can Nylon burn with the smell of burning hair??

Ans 11:

Class : Class 8
Correct answer is A

Ans 12:

Class : Class 8
Nylon should neither have a smell of burning hair nor the smell of burning paper. Nylon has a celery or plastic-like cell. Hence the correct answer is D. But on the other hand when acrylic burns, it shrinks and converts into black beads. On this contrast, the correct answer will be B with respect to acrylic and D with respect to Nylon. There is definitely an error in the options of the answers!

Ans 13:

Class : Class 8
(D)

Ans 14:

Class : Class 9
Supposed to be D

Ans 15:

Class : Class 8
How is this possible Nylon burns with smell of hair???
