Assertion : The speedometer of an automobile measures the average speed of the automobile. Reason : Average velocity is equal to total distance divided by total time taken.

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.
