The energy gap is that sufficient energy which is acquired by the charge carrier to move its higher energy level.

It is the energy between valance band and conduction band!

It is the energy required to move an electron from valance band to conduction band.

Energy gap is the minimum energy required to move an electron from the valence band to the conduction band.
