Best answer
Correct option is (a) 100 ^0C

To elaborate: Nylon-66, PET and PAN all have Tg around 100 ^0C. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs. It is always lower than the melting temperature, of the crystalline state of the material, if one exists.
