Solution

The correct option is D Both Assertion and Reason are incorrect
The resistivity of a semiconductor decreases with temperature. This is because of increasing temperature, the electrons in the valence band gain sufficient thermal energies to jump to the conduction band. As the number of electrons in the conduction band increases, so conductivity increases and resistivity decreases. Both assertion and reason are incorrect.
