If a sample of germanium and a sample of silicon have the same impurity density and are kept at room temperature

[A].	both will have equal value of resistivity
[B].	both will have equal negative resistivity
[C].	resistivity of germanium will be higher than that of silicon
[D].	resistivity of silicon will be higher than that of germanium

Answer: Option D

Explanation:

Resistivity of silicon is more than that of germanium.
