Choose the false statement from the following

Options

A. The conductivity of a semiconductor increase with increase in temperature
B. In conductors the valence and conduction bands overlap in most of the cases
C. Substances with energy gap of the order of 10 eV are insulators
D. The resistivity of a semiconductor increases with increase in temperature

Answer

D

Explanation

For a semiconductor, the conductivity increases with temperature and hence its resistivity decreases with increase in the temperature
