A) Continental drift.
Rationale: Movement and rearrangement of continents changes the shape and connections of ocean basins, opening/closing seaways and altering basin geometry and seafloor topography — all of which directly redirect and reorganize ocean currents (e.g., the closing of the Isthmus of Panama changed Atlantic circulation). The other choices affect climate and can indirectly influence currents but do not directly reconfigure ocean pathways.
