Assertion : Electron has higher mobility than hole in a semiconductor. Reason : Mass of electron is less than the mass of hole.
  1. both assertion and reason are true and reason is the correct explanation of assertion.
  2. both assertion and reason are true but reason is not the correct explanation of assertion.
  3. assertion is true but reason is false.
  4. both assertion and reason are false.
