In a P-type semiconductor, the acceptor impurity produces an energy level

Question

In a P-type semiconductor, the acceptor impurity produces an energy level (A) just below the valence band (B) just above the conduction band (C) just below the conduction band (D) just above the valence band

In p-type semiconductor, valency = 3, thus there is one unformed bond or hole created. This hole is in valence band and is able to cause hole current. The energy levels of acceptor are in forbidden gap just above valence band
