Holes are majority carriers and trivalent atoms are the dopants.

(D) In a $p$-type semiconductor,the material is doped with trivalent impurity atoms (such as Boron,Aluminum,or Indium).These trivalent atoms create vacancies in the crystal lattice,which act as holes.Therefore,holes become the majority charge carriers,while electrons are the minority charge carriers.Thus,the correct statement is that holes are majority carriers and trivalent atoms are the dopants.
