Solution
The correct option is BInsulators, Semiconductors, Conductors In the case of insulators, the energy gap is very large while in case of semiconductors energy gap is very short.This energy gap refers to the energy difference between valence band and conduction band.
Whereas in semiconductors, this band gap value is in between that of conductors and insulators.
