The correct answer is D) California Current. The California Current is a cold ocean current flowing southward along the west coast of North America. The other options, Brazilian Current, Gulf Stream, and North Equatorial Current, are all warm ocean currents.
Ocean currents are classified as warm or cold based on whether they carry water from warmer regions to colder regions or vice-versa. The California Current originates in cooler northern waters and flows towards the equator.
Cold currents typically flow towards the equator along the western coasts of continents in tropical and subtropical latitudes, while warm currents flow towards the poles, often along the eastern coasts of continents.
