B Correct answer
Explanation

Ocean currents are primarily driven and modified by the Earth's rotation (Coriolis effect), atmospheric pressure and wind patterns, and differences in water density (temperature and salinity). The Earth's revolution affects seasonal cycles but does not directly modify the mechanics of current flow.
