This gap is a positive energy. Due to this gap, the atom becomes a positive ion. The positive gap created here is called a hole because it is the hole created by the atom that left its place.

B is correct answer because free electrons are in conduction band. Electrons jump from valence band to conduction band leaving a gap in valence orbit called hole. The hole is the absence of an electron in valence band. Hole current occurs at the valence level.
