Solution
The correct option is A SONAR
The device which uses ultrasonic waves to measure the distance, direction and speed of underwater objects is known as SONAR. SONAR stands for Sound Navigation and Ranging.
It is used to find depth of the sea and to locate underwater hills, valleys, icebergs, sunken ships etc.
RADAR uses electromagnetic waves for echolocation. Also, it must be noted that RADAR is not useful underwater because electromagnetic waves die in water very quickly.
