V. W. Ekman is credited with developing the theory of:

A. sea floor spreading

B. global tectonics

C. wind-driven ocean currents

D. seismic profiling

C

Explanation:

his theory explains the frictional effects in the ocean with the Coriolis force (spiral wind patterns)

C. wind-driven ocean currents

Explanation:

Ekman developed a theory that winds are the main source for the ocean's current circulation and transportation occurs when the ocean surface gets friction produced by the motion of the winds. And this also leads to the upwelling and downwelling of warm and cold waters.
