It would be all of the above.
The correct answer is - from west to east.
On the globe that is presented, the arrows clearly point to a movement of the air masses from west towards east. Both on the Northern Hemisphere and the Southern Hemisphere, the movement is in the same direction, and also, there's no difference in the direction of the cold air masses and the warm air masses. These winds are known as westerlies, prevailing westerlies, or as anti-trade winds.
These winds have opposite movement from the winds that appear on the Equator, as those winds move from east towards west.
