Solution

The correct option is B are less than
n-Type conductor is made by doping an intrinsic semiconductor with pentavalent impurities
hence in an n-type semiconductor, electrons are the majority corners and holes are minority corners
so no. of holes are less than no. of electrons.

The correct option is B are less thann-Type conductor is made by doping an intrinsic semiconductor with pentavalent impurities hence in an n-type semiconductor, electrons are the majority corners and holes are minority corners so no. of holes are less than no. of electrons.
