Hint: A semiconductor is a material whose conductivity lies in between that of an insulator and a metals. They have holes and electrons, which contribute to their unique property .By the method called doping; the conductivity of these semiconductors can be increased.

Complete answer:
 We know that semiconductors are a type of metal which can conduct electricity, they lie between insulators and metals. The resistivity of any semiconductor materials decreases with rise in temperature, thus the semiconductor may malfunction.
Doping is a technique of adding impurities to the crystal; this changes the properties of the crystal. Thus resulting in two types of semiconductors namely, the p-type and the n-type. Where p-type has more number of holes as compared to the parent semiconductor and the n-type has more number of electrons as compared to the parent semiconductor.

Thus clearly option D. holes is the correct answer.

Additional Information:
Fermi level is usually used to denote the relationship between the property of the material, mainly the flow of charges of the electronic structure of the semiconductor, to understand solid-state physics. Also the Fermi-levels are generally close to the valence bonds

Semiconductors are materials which are made up of holes and electrons. In the p-type semiconductor also called the acceptors, doping is done to increase the number of holes in the semiconductor; hence holes are the majority carriers. Whereas, the n-type semiconductor also called the donors, doping is done to increase the number of electrons in the semiconductor; hence electrons are the majority carriers.
