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 2:
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!
