(B) $p-$type semiconductors are obtained by doping group $14$ elements like silicon or germanium with group $13$ elements (electron-deficient impurities) such as $B, Al, Ga,$ or $In$. Since boron belongs to group $13$,doping silicon with boron creates electron holes,resulting in a $p-$type semiconductor.
