Electrons are majority carriers and pentavalent atoms are dopants.

(B) In an $n-$type semiconductor,the intrinsic semiconductor (like $Si$ or $Ge$) is doped with pentavalent impurity atoms (like $P, As, Sb$).These pentavalent atoms provide extra electrons to the conduction band.Therefore,electrons become the majority charge carriers,while holes are the minority charge carriers.Thus,the correct statement is that electrons are majority carriers and pentavalent atoms are dopants.
