Statement I Band gap in germanium is small. Statement II The energy spread of each germanium atomic energy level is infinitesimally small.

Options

  1. AStatement I is true, Statement II is true, Statement II is a correct explanation for Statement I
  2. BStatement I is true, Statement II is true, Statement II is not a correct explanation for Statement I
  3. CStatement-I is true, Statement II is false
  4. DStatement-I is talse, Statement II is true

Correct answer

C. Statement-I is true, Statement II is false

Step-by-step solution

Germanium, semi-conductor substance, has small band gap in comparison to insulator (non-metal). On moving top to bottom in the group 14 band gap decreases.
