For a p-type semiconductor, which of the following statements is true? (a) Holes are the majority carriers and trivalent atoms are the dopants. (b) Holes are the majority carriers and pentavalent atoms are the dopants. (c) Electrons are the majority carriers and pentavalent atoms are the dopants (d) Electrons are the majority carriers and trivalent atoms are the dopants.

Answer: (a). p-type is made by adding trivalent (acceptor) atoms such as B, Al, In. Each acceptor creates a hole, so holes are the majority carriers. So the answer is (a).
