Doping of silicon with \( \mathrm{P} \) or \( \mathrm{Al} \) increasing the conductivity. The difference in the two cases is
(A) \( \mathrm{P} \) is non - metal whereas \( \mathrm{Al} \) is a metal
(B) \( \mathrm{P} \) is a poor conductor while \( \mathrm{Al} \) is conductor
(C) \( \mathrm{P} \) gives rise to extra electrons while \( \mathrm{Al} \) gives rise to holes
(D) \( \mathrm{P} \) gives rise to holes while \( \mathrm{Al} \) gives rise to extra electrons
