Assertion : A p-n junction with reverse bias can be used as a photo-diode to measure light intensity. Reason : In a reverse bias condition the current is small but it is more sensitive to change in intensity of incident light.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIfboth assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.
