Answer: Option C
Explanation:
The main reason by which the ocean currents are formed is the rotation of earth. The earth rotates on its own axis and due to this reason there is a huge mixing of the water from the equator and poles which is termed as ocean currents.
Ocean currents are important as it controls the global temperature. The water at the equator is hot and the water at poles are cold.
Due to the rotation of the earth the water and air moves from the colder regions towards the hotter region and hotter to colder and this causes ocean currents.
