Doping of a semiconductor material means

[A].	that a glue-type substance is added to hold the material together.
[B].	that impurities are added to increase the resistance of the material.
[C].	that impurities are added to decrease the resistance of the material.
[D].	that all impurities are removed to get pure silicon.

Answer: Option B

As intrinsic semiconductors having less conductivity we are adding inpurities to it to increase conductivity.increasing conductivity means decreasing the resistance of the material. So option C is correct.

Doping means to increase the current in material. i.e. R=V/I. So increase in current causes decreases in the resistance.
