The Temperatures at the Equator Remain Warm Year-Round Because

The temperatures at the equator remain warm year-round because:

A) Earth's rotation on a tilted axis creates more atmospheric friction at the equator.
B) Earth's natural curvature places the equator nearer the sun.
C) the sun shines over the equator more hours in the day.
D) there are large oceans near the equator that absorb large amounts of heat.
E) sunlight strikes the equator relatively directly with little seasonal variation.
