B. Cold water current:

The West Wind Drift also called Antarctic Circumpolar Current is the current which circles the entire globe and largest of all kind.

The West Wind Drift / Antarctic circumpolar current carries more water as compare to other currents in the world joining three ocean basin namely: Atlantic, Pacific and Indian. The West Wind Drift current's water is cold and thick because it is near to Antarctica due to which the water around it is freezing and having no salt in it. Due to its enclosure to Antarctica it pushes away hot water which helps it in keeping its large Ice sheet intact.
