Match the List I with List II

Choose the correct answer from the options given below:

Intrinsic Semiconductor has its Fermi level exactly in the center of the band gap $$\implies$$ (A) $$\to$$ II

$$n$$-type semiconductor has donor levels near the conduction band, shifting the Fermi level upward $$\implies$$ (B) $$\to$$ III

$$p$$-type semiconductor has acceptor levels near the valence band, shifting the Fermi level downward $$\implies$$ (C) $$\to$$ I

Metals have a partially filled conduction band or overlapping bands, placing the Fermi level directly within $$\implies$$ (D) $$\to$$ IV
