Show answer & explanation
Correct answer: B
Ultrasonic sensors are the standard technology used in vehicular parking assist systems (often called parking sensors).
How it works: These sensors are embedded in the front and rear bumpers of a vehicle. They emit high-frequency sound waves (ultrasound) that bounce off nearby obstacles. By measuring the time it takes for the echo to return, the system calculates the exact distance to the obstacle and alerts the driver with audible beeps or visual indicators on the dashboard.
