Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The audible range of sound for human beings extends from about $20 H z - 20, 000 H z$ . Ultrasonic waves are longitudinal waves of frequency greater than the audible range for humans $(20, 000 H z)$ .
Therefore, both assertion and reason are correct but the reason is not the correct explanation for reason.
