Question

Statement I: Silicon is preferred over germanium for making semiconductor devices. Statement II: The energy gap for germanium is more than the energy gap of silicon. (A) If both statements are true and statement II is the correct explanation of statement I (B) If both statements are true but statement II is not the correct explanation of statement I (C) If statement I is true but statement II is false (D) If both statements are false

The energy gap for germanium is less (0.72 eV ) than the energy gap of silicon ( 1.1 eV ). Silicon is preferred over germanium for making semiconductor devices because they are abundantly available in nature, do not get easily damaged by heat and cut off current is very low.

Q. Statement I: Silicon is preferred over germanium for making semiconductor devices.
Statement II: The energy gap for germanium is more than the energy gap of silicon.

If both statements are true and statement II is the correct explanation of statement I

If both statements are true but statement II is not the correct explanation of statement I

If statement I is true but statement II is false

If both statements are false

The energy gap for germanium is less $(0.72 e V)$ than the energy gap of silicon ( $1.1 e V$ ). Silicon is preferred over germanium for making semiconductor devices because they are abundantly available in nature, do not get easily damaged by heat and cut off current is very low.
