C.
One sunspot is an area of cooler temperature than the surrounding surface and the other is an area of higher temperature than the surrounding surface.
D.
One sunspot is an area of rising gas from the surface and the other is an area of falling gas into the surface.

A.
2 seconds ago

B.
100 years ago

C.
100,000 to 1 million years ago
