The correct answer is (b), Rotation of the Earth.
The Coriolis effect is an apparent deflection of objects moving in a straight line on a rotating object. It is caused by the Earth’s rotation, which causes the Earth’s surface to move faster at the equator than at the poles. This difference in speed causes objects moving in a straight line to appear to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
The Coriolis effect is most noticeable for objects moving over long distances, such as airplanes and hurricanes. It can also be seen in the way that rivers curve and the way that wind
