The correct answer is (b), Banguela.
The Gulf Stream, Norwegian, and Florida currents all flow in the North Atlantic Ocean. The Gulf Stream is a warm, fast-moving current that flows from the Gulf of Mexico up the east coast of the United States and then across the Atlantic Ocean to Europe. The Norwegian Current is a cold, slow-moving current that flows from the Arctic Ocean down the west coast of Norway. The Florida Current is a warm, fast-moving current that flows from the Gulf of Mexico up the east coast of Florida and then across the Atlantic Ocean to the Azores.
The Banguela Current is a cold, slow-moving current that flows along the coast of Angola in Africa. It is not part of the North Atlantic Ocean.
