Hint In a p-type semiconductor doping is the process that changes an intrinsic semiconductor to an extrinsic semiconductor. During the process of doping the impurity atoms are moved and the atoms are introduced to the intrinsic semiconductor
Complete step by step answer In p-type semiconductor the majority of the conduction occupies the holes. So, here the electrons occupy a small portion in a conduction. A substance which is solid can conduct electric current only if it contains the charged particles and the electrons which are free to move about the substance. It is not attached to the electrons. During this process of doping, impurities act as the either donors or acceptors to the intrinsic semiconductor. In general acceptor impurity atoms have fewer valence electrons than the atoms. Impurity atoms are replaced in the intrinsic semiconductor. In p-type semiconductor excess holes to the intrinsic semiconductor. Because of the excess holes increase the hole carrier concentration of the semiconductor. It has been created as a p-type semiconductor. Therefore, in a p-type semiconductor conduction is due to the greater number of holes and lesser number of electrons.
Hence, from the above options, option A is correct.
Note In p-type semiconductors are created by doping an intrinsic semiconductor with an electron acceptor element during the process of doping. So, here the term is called the positive charge as a hole.
