Solution
The correct option is A convection current
Ocean currents are caused by the setting of convectional current in water.
Convectional current are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is the movement that creates circulation pattern known as convection current in atmosphere, water and mantle of Earth.
