Solution

The correct option is D sound waves
Sonar (sound navigation and ranging) is a technology that uses acoustical (ultrasonic sound waves ) waves to sense the location of objects in the ocean. The simplest sonar devices send out a sound pulse from a transducer, and then precisely measure the time it takes for the sound pulses to be reflected back to the transducer. Which helps in calculating distance of object.
