A car is to a traffic light what the sun is to:

A. a solar eclipse.
B. a solar panel.
C. a star.
D. a mirror.

What is the best answer and please explain why?
While all of them are bad analogies and the correct answer should be "None of the above", but out of all of the choices, "A" is the best answer.

From an observer on earth, a solar eclipse would control the amount of light which reaches Earth, just like traffic lights control the amount of car traffic on the road, although that is still quite a stretch.
