Which one of the following is a warm ocean current?

Ocean currents are classified as warm or cold based on their temperature relative to the surrounding waters. The Kuroshio Current, also known as the Japan Current, is a warm, powerful western boundary current in the North Pacific Ocean. It originates from the North Equatorial Current and transports warm tropical waters northward along the coasts of Taiwan and Japan, similar to the Gulf Stream in the Atlantic. In contrast, the Labrador Current is a cold current that flows south from the Arctic along the northeast coast of North America [2]. The Peru Current (Humboldt Current) is a cold current flowing northward along the western coast of South America [1]. The Benguela Current is also a cold current found on the west coast of southern Africa. Therefore, among the given options, only the Kuroshio Current is a warm ocean current.
