Answer: 2. Holes are the majority carriers and trivalent atoms are the dopants.

A p-type semiconductor is made by doping silicon or germanium with a trivalent impurity (such as B, Al, In). Each dopant atom leaves one missing bond, a hole. So holes are the majority carriers. Pentavalent dopants make n-type material, in which electrons are the majority carriers.
