Answer: It has holes in majority and electrons in minority.

Explanation: A p-type semiconductor is formed by doping an intrinsic semiconductor with trivalent impurity for example Boron, Aluminium, Indium, Gallium etc. Gallium or Boron is a common p-type dopant for silicon. It has large numbers of holes provided by the trivalent atoms which are electrically neutral and because of these electrically neutral trivalent atoms the total electrical charge is neutral.
