Answer:
The equator.
Step-by-step explanation:
"The equator receives the most solar radiation in a year. The difference in the amount of solar energy the land receives causes the atmosphere to move the way it does."
I wasn't so sure about this question. During my research, the internet says atmosphere, equator, and then oceans. I believe it's more of the equator than anything, but there are three choices to choose from.
I hope this helps!
