In the given map, which one of the following pairs of ocean currents is shown?

The map most plausibly shows the Benguela and Guinea currents because both are Atlantic currents on the west coast of Africa and therefore appear together on maps of the eastern South and equatorial Atlantic. Reference material lists both the Benguela and the Guinea currents among Atlantic Ocean currents, confirming their co‑occurrence in the same basin. Detailed studies of the Benguela Current place it in the southwestern South Atlantic, linked into the South Atlantic subtropical gyre and interacting with flows around southern Africa, which aligns with a depiction that would also include the equatorial Guinea Current to the north [1]. Thus the pair Benguela & Guinea is the consistent Atlantic pairing on such a map.
