Which of the following is/are warm ocean current(s) ? 1. Alaska Current 2. Agulhas Current 3. Falkland Current 4. West Australian Current Select the answer using the code given below :

Ocean currents are classified as warm or cold based on their temperature relative to surrounding waters and their direction of flow. The Alaska Current is a warm current that flows anti-clockwise along the coasts of British Columbia and Alaska in the North Pacific. The Agulhas Current is a major warm western boundary current in the Indian Ocean, formed by the merging of branches near Madagascar. Conversely, the Falkland Current (or Malvinas Current) is a cold current that branches from the West Wind Drift and flows north along the Argentinian coast [3]. The West Australian Current is also a cold current that flows northward along the western coast of Australia toward the equator. Therefore, only the Alaska and Agulhas currents are warm currents, making option 2 the correct choice.
