The correct answer is confirmed by the illumination of the car latch light, which turns green when a coupling has been successful. This indicator is an essential part of the safety mechanisms in place for train operations. It provides a clear, visual confirmation that the two train cars are securely connected, ensuring operational safety and preventing accidents that could arise from an improper coupling.

While listening for a click is often a common practice in various train operations, it is not as reliable as the electronic confirmation provided by the car latch light. Similarly, visual inspections, although important, can sometimes miss subtle misalignments or issues that the electronic system would catch. Completing a test run can demonstrate if the train operates correctly, but it does not directly confirm the integrity of the coupling. Therefore, the green illumination of the car latch light is the most definitive and direct method to confirm a successful coupling.
