Answer:
A
Explanation:
Earth does not move closer to the sun via orbiting. The factor that creates seasons is it's axis tilt, which makes part of the Earth receive more sun than the other lower half. That's why the equator has the most sun overall. Every day has the same 24 hours but during the summer the days are longer and it is exposed to more sunlight.
