PLZZ help me with number 7!!

B

Explanation:

I have never heard of volcanoes on Mercury, and there couldn't be water since it would evaporate immediately. This means it either creates its own heat or it's because it's so close to the sun. Now, if you think about it, we don't create our own heat, we only trap it. So it is safe to assume that it's so hot because it's so close. Hope this helps!

The answer is B because it's the closest to the sun

yes? sounds right, but you didn’t ask a question.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
