Adeep currents
Csurface currents
Bwind currents
Ddensity of currents

Verified Answer :

Well, at first glance I'd be tempted to say all of them. The C "force" is why weather maps show winds blowing parallel to isobars and thus around centres of high and low pressure. (You'd expect, or at least I would, that air would flow from high to low pressures, not round them ... )

C.surface currents are the answer
