Question
Assertion : Silicon is preferred over germanium for making semiconductor devices.
Reason : The energy gap for germanium is more than the energy gap of silicon.

Answer

(c) The energy gap for germanium is less $(0.72 \mathrm{eV})$ than the energy gap of silicon $(1.1 \mathrm{eV})$. Therefore, silicon is preferred over germanium for making semiconductor devices.
