The correct answer is B) Eastern Australian Current.
Ocean currents can be classified as warm or cold based on their temperature relative to the surrounding water, which in turn influences the climate of adjacent landmasses. Warm currents typically flow from the equator towards the poles, while cold currents flow from the poles towards the equator. The Western Australian Current, Benguela Current, and Peru Current are all prominent cold currents flowing towards the equator along the western coasts of continents in the Southern Hemisphere (or South America in the case of Peru). The Eastern Australian Current, however, flows southwards along the east coast of Australia and is a warm current originating from tropical waters.
Cold currents bring cold water to warmer regions, often leading to arid conditions on adjacent coasts (e.g., Atacama Desert near Peru Current, Namib Desert near Benguela Current). Warm currents bring warm water to colder regions, generally leading to more humid and mild conditions on adjacent coasts (e.g., the British Isles influenced by the North Atlantic Drift).
