The correct choice indicates that turn signals, brake lights, and four-way flashers can be checked simultaneously. This is significant because when evaluating a vehicle's lighting system, these particular lights are designed to work in conjunction with one another for safety and signaling purposes.

Turn signals are essential for indicating a change in direction to other drivers, while brake lights provide a clear visual warning to those behind when the vehicle is slowing down or stopping. The four-way flashers, or hazard lights, serve as a warning to others that the vehicle is experiencing an issue or is stationary in a potentially hazardous situation. Testing these lights together allows for a comprehensive check of the vehicle’s signaling and visibility in a variety of driving conditions.

In contrast, the other combinations involve lights that typically do not operate together in the same context. For example, headlights generally serve a different function and are not used in conjunction with brake lights or fog lights in the same manner. Understanding how these different lights operate together is crucial for ensuring that they are functioning correctly to maintain road safety and compliance with regulations.
