The correct option is D Holes and electrons
In a P−type semiconductor, a hole is created for every dopant atom added to it. So, the number of holes is greater than the number of electrons.
When current flows through it, most of the current flows due to movement of holes and a small fraction of current flows due to the movement of the electrons.
So we say that, in a P−type semiconductor, holes are majority charge carriers and electrons are minority charge carriers.
Hence, (D) is the correct answer.
