Assertion : Electron requires 0.7 eV to jump from conduction band to valence band. Reason : The band gap of the sample is 0.7 eV.

Both (A) and (R) are true and (R) is the correct explanation of (A). Both (A) and (R) are true but(R) is NOT the correct explanation of (A). (A) is true but (R) is false. (A) is false but (R) is true.

(A) is false but (R) is true.

Note : Electron requires 0.7 eV to jump from valence band to conduction band.
