The correct answer is D) Icebergs may travel in a direction many degrees different from the sea ice. This is because icebergs are primarily influenced by ocean currents, which can differ significantly in direction from the wind-driven movement of sea ice. The underwater bulk of an iceberg allows it to be affected more by subsurface currents, which can cause the iceberg to drift in a different direction than the surrounding sea ice on the surface. In contrast, the other options assume the iceberg and sea ice will move in the same general direction, which is not always the case due to this difference in driving forces.
