Correct Answer – B
Holes are minority carriers and pentavalent atoms are depends

Correct Answer – C
The n-type semiconductor can be produced by doping an impurity atom of valence 5 i.e. pentavalent atoms.
i.e. phosphorus.

Correct Answer – C
In a `n`-type semiconductor holes are minority carriers and pentavalent atoms are dopants.

Correct Answer – C

The correct statement is (c).
In an-type silicon, the electrons are the majority carriers, while the holes are the minority carriers. An n-type semiconductor is obtained when pentavalent atoms, such as phosphorus, are doped in silicon atoms.
