Correct Answer: B. The red light is about to appear — stop if you can do so safely
Yellow means 'prepare to stop.' You should stop if you can do so safely; if you are too close to the intersection to stop safely, continue through with caution. Accelerating on yellow is a major cause of intersection collisions.
Why the other answers are wrong

- D.Proceed with the same caution as greenYellow is not the same as green; you should be preparing to stop, not maintaining speed as on green.
