Correct option is B
RADAR (Radio Detection and Ranging) is primarily used to detect objects such as aircraft, ships, and weather formations by bouncing radio waves off of them and measuring the return signals. It plays a crucial role in military applications, especially in detecting fighter planes and other flying objects. It is also widely used in weather forecasting, air traffic control, and automotive systems.
RADAR systems work by transmitting radio waves and then receiving the signals that bounce back from objects, helping to determine their location, speed, and direction.
