What best describes a self-driving car?

• A. A car with a driver performing all tasks.
• B. A driverless car that uses sensors to navigate without human intervention.
• C. A manual vehicle with automated seat adjustments.
• D. A car that relies solely on GPS without sensors.

Answer: (B)

A self-driving car is an autonomous vehicle that can operate without a human driver, using sensors and computer systems to perceive its surroundings, make decisions, and control the vehicle.

That description fits best because it conveys both the lack of a human driver and the use of sensors to navigate. Self-driving technology relies on sensors such as cameras, radar, and lidar to detect objects, lanes, and obstacles, along with software that localizes the car in its environment and plans a safe route.

The other ideas don’t capture true autonomy. A car with a driver performing all tasks is just a conventional vehicle requiring a human driver. A manual vehicle with automated seat adjustments involves some comfort features but still requires a person to drive. Relying solely on GPS without sensors is not enough for safe, autonomous operation because GPS cannot provide real-time awareness of the immediate surroundings.
