Correct Answer

Explanation

A p-type semiconductor is characterized by the presence of positively charged "holes" as the majority charge carriers, which are created by doping the semiconductor material with acceptor impurities. This results in an excess of positive charge carriers, as opposed to the excess of negative charge carriers in an n-type semiconductor.
