Vedclass · Answer

(C) In a $p-$type semiconductor,the material is doped with trivalent impurity atoms (like Boron,Aluminum,etc.).These trivalent atoms create vacancies in the valence band of the semiconductor crystal lattice.These vacancies are known as holes.Since the number of holes created by the doping process is significantly higher than the number of thermally generated electrons,holes act as the majority charge carriers in $p-$type semiconductors.
