Which of the statements given is true for $p$-type semiconductors?
(a) Electrons are majority carriers and trivalent atoms are the dopants.
(b) Electrons are minority carriers and pentavalent atoms are the dopants.
(c) Holes are minority carriers and pentavalent atoms are the dopants.
(d) Holes are majority carriers and trivalent atoms are the dopants

Here, (d) is the correct explanation.

The majority carriers in a p-type semiconductor are holes, while the minority carriers are electrons. Trivalent atoms such as aluminium in silicon atoms are used to make p-type semiconductors.
