I'm gonna have to go with D as well. Gotta love those self-driving cars and their fancy closed-loop systems keeping us safe on the road.

Option D is the clear winner here. Cruise control is the textbook example of a closed-loop system in action.

Haha, option A about testing hazard lights? That's like testing whether the car turns on by checking if the dashboard lights up. Not very closed-loop if you ask me.

Yeah, option A seems a bit too basic for a closed-loop system.

I agree, D is the best answer. Closed-loop systems use feedback to automatically correct errors or disturbances, which is exactly what a cruise control does.

I'm not sure, I think option A could also be a valid example of a closed-loop system.

Option D seems like the most typical closed-loop system example. Cruise control constantly monitors and adjusts the speed to maintain a target, just like a closed-loop system would.
