Answer:
The intrinsic Fermi energy is slightly below the center of the bandgap ( option A )
Step-by-step explanation:
Given that the effective mass of holes is > than the effective mass of electrons in a semiconductor the Intrinsic Fermi energy is slightly below the center of the bandgap.
Intrinsic Fermi energy is experienced/present in the occupation of energy levels in the valence or conduction bands of an intrinsic conductor
