In a p type material the Fermi level is 0.3 eV above valence band. The concentration of acceptor atoms is increased. The new position of Fermi level is likely to be

[A].	0.5 eV above valence band
[B].	0.28 eV above valence band
[C].	0.1 eV above valence band
[D].	below the valence band

Answer: Option B

Explanation:

Addition of acceptor atom brings Fermi level closer to valence band.
