In insulators there is a large forbidden gap in between conduction band n vacancy band. So practically it s impossible for electron to jump from valence band to conduction band. So such materials cannot conduct so these are called insulators e.x diamond, glass wood.

For insulator the depletion region width is high between the valance band and conduction band. So there is no flow of free electrons.

Whai is free electron?

All of the above should be the answer as there is no conductor/semiconductor that doesn't oppose electron in the practical scenario.

Conducted is not opposes the free elecrons and semiconductor is both acts as opposes the free elecrons are not but insulator is purely opposes the free elecrons.
