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

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

C

Explanation

The energy gap for germanium is less `(0. 72eV)` than the energy gap of silicon `( 1.1eV)` . Therefore, silicon is preferred over germanium for making semiconductor devices.
