"Surface currents" has the greatest impact on climate.

Option D

Explanation:

The major wind belts but not daily winds are responsible for surface currents. Mostly those winds keep blowing in the same direction in order to keep moving water in the same direction. In the surface currents water is pushed in the direction of the major wind belts like

Trade winds: It flows between the Equator and 30 degree N and 30 degree S, from east to west in direction.Polar easterlies: It flows between 50 degree N and 60 degree S of the Equator and the north and south pole from east to west in direction.Westerlies: It flows in the middle latitudes from west to east.

Currents generally carry warm water to the poles from the tropics and bring cold water down to the equator. A surface current warms or cools the air above it, affecting the terrestrial atmosphere near the coast and influence climate through the movement of cold and warm water around the globe.
