Triple

Target class: former large inland sea
Context triple: [Aral Sea, instanceOf, former large inland sea]

• A. former lake chosen
  A former lake is a geographic area that once contained a standing body of water but has since dried up, drained, or been otherwise transformed, leaving behind distinct geological and ecological remnants of its past.
• B. body of water
  A body of water is a naturally or artificially formed, relatively distinct accumulation of water—such as a lake, sea, river, or pond—occupying a definable area on the Earth's surface.
• C. oceanic basin
  An oceanic basin is a large, geologically defined depression on the seafloor that collects ocean water and is bounded by continental margins, mid-ocean ridges, and other submarine features.
• D. post-glacial stage of the Baltic Sea
  The post-glacial stage of the Baltic Sea is the developmental phase following the last Ice Age during which the retreat of continental ice sheets, isostatic land uplift, and changing sea levels transformed the basin from a glacially dammed lake into a brackish marginal sea with evolving coastlines and ecosystems.
• E. freshwater lake
  A freshwater lake is a naturally occurring inland body of standing water with low salt concentration, supporting diverse aquatic ecosystems and often serving as a critical resource for wildlife and human use.
• F. None of above.
