Answer:
Option (B)
Step-by-step explanation:
The temperature is the important factor that generates the convection current in the ocean water. Due to the global ocean water circulation, the water in the ocean gets heated up. As a result of which the water becomes warm and less dense. It then rises up towards the upper portion of the ocean body. This warm water then moves over the deeper cooler water by the action of wind. This motion of ocean current releases its heat energy into the environment. This water then becomes cold and denser and eventually sinks to the bottom of the ocean. This continuous motion of water is known as the convection current that forms in the ocean.
Thus, the correct answer is option (B).
