Which Best Explains The Coriolis Effect? Will give brainliest if answered now!

A) Air flow is either east-west or west-east due to the revolution of the earth around the sun.

B) Air flow is either north-south or south-north due to the uneven heating of the earth's surface.

C) Air flow is either vertical or horizontal depending upon whether the winds blow in the northern hemisphere or the southern hemisphere.

D) Air flow is not exactly north-south or south-north because the earth spins below, slightly skewing the air flow pattern.
