Which one among the following is a cold current in the Atlantic Ocean?

The Benguela Current is a cold current located in the South Atlantic Ocean. It flows northward along the west coast of South Africa, eventually joining the South Equatorial Current to complete the South Atlantic gyre. In contrast, the Gulf Stream is a warm current in the North Atlantic that flows along the east coast of the USA [4]. The Brazil Current is also a warm current, flowing southward along the east coast of South America [2]. While the Peru Current (also known as the Humboldt Current) is indeed a cold current, it is located in the South Pacific Ocean, not the Atlantic [4]. Ocean currents are generally classified as cold when they bring water from higher latitudes toward the equator, typically found on the western coasts of continents in low to middle latitudes [5].
