The correct answer is the option 2 - False.

Fermi energy is the energy that separates the empty states of the conduction band from the occupied states in the valence band at absolute temperature i.e., at 0 K.

Ina p-type semiconductor, there are many holes in the valence band when compared to the electrons present in the conduction band. So, the possibility of finding an electron around the conduction band is less than the possibility of finding a hole near the valence band. So, the Fermi level of a p-type semi-conductor is closer to the valence band. Therefore, the Fermi level of a p-type semiconductor is lower than that of a n-type semiconductor.
