(B) Self-driving cars
Self-driving cars are the best example of Robotics and AI working together, as they use AI for decision-making and robotic systems for physical navigation and control.
The answer is (B) Self-driving cars because they integrate AI (for perception, data processing, and decision-making) with robotic hardware (sensors, actuators, steering/braking systems). Telephones, bulbs, and printing machines do not combine both robotics and AI. In MCQs, write the option letter and a brief justification for full marks.
