D. Because of the Coriolis Effect.

The apparent deflection arises from Earth's rotation: air moving north or south keeps its original eastward speed (angular momentum), so relative to the rotating surface it is displaced to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
