Phrase: Antarctic Polar Front | Statement: [Antarctic Convergence, alsoKnownAs, Antarctic Polar Front]

Target entity: Antarctic Polar Front
Context triple: [Antarctic Convergence, alsoKnownAs, Antarctic Polar Front]

• A. Subantarctic Front
  The Subantarctic Front is a major oceanographic boundary in the Southern Ocean that separates relatively warm, salty subtropical waters from cooler, fresher subantarctic waters and plays a key role in global heat and nutrient transport.
• B. Antarctic Convergence chosen
  The Antarctic Convergence is a major circumpolar oceanic boundary where cold Antarctic waters meet and sink beneath warmer sub-Antarctic waters, creating a sharp gradient in temperature and marine ecosystems.
• C. Antarctic Circumpolar Current
  The Antarctic Circumpolar Current is the powerful, continuous ocean current that flows eastward around Antarctica, connecting the Atlantic, Pacific, and Indian Oceans and playing a key role in global climate and ocean circulation.
• D. American-Antarctic Ridge
  The American-Antarctic Ridge is a mid-ocean ridge in the South Atlantic–Southern Ocean region where the American and Antarctic tectonic plates diverge, forming part of the global system of seafloor spreading centers.
• E. Malvinas Current
  The Malvinas Current is a cold, northward-flowing ocean current off the southeastern coast of South America, formed by subantarctic waters and strongly influencing the region’s climate and marine ecosystems.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
