Step-by-step explanation:
A green traffic light that has been green for some time is stale, likely to turn yellow. When a traffic light turns green, it typically stays green for a certain period of time before transitioning to yellow. Yellow signals caution and warns drivers that the light will be turning red soon. This allows them to slow down and prepare to stop.
Hence the correct answer is option C
