SONAR because they are blind so they use sonar waves to detect the object and also with the help of reflection (it send sonar waves first the sonar waves are reflected by the object then only it identifies the object.

Answer: The correct option is B. SONAR (Sound Navigation & Ranging)
Step-by-step explanation:
SONAR ( sound navigation ranging) uses ultrasonic waves i.e. sounds having frequency greater than 20,000 Hz. The reasons are:-
1. They can penetrate water to long distances (because of their high frequency and very short wavelength) unlike ordinary sound waves or infrasonic waves.
2. Sound of these waves do not get mixed with engine noises or other sounds made by the ship. So, no confusion arises as these waves are not audible by human ear.
Hope it helps!
