Assertion : The logic gate NOT can be built using diode. Reason : The output voltage and the input voltage of the diode have 180^ phase difference.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both 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.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

In diode the output is in same phase with the input therefore it cannot be used to built NOT gate.
