The exceptional salinity of which major lake is primarily due to being part of an endorheic basin?

💡 Explanation:

The Dead Sea is a terminal (endorheic) lake, meaning water flows in but does not flow out to an external body like an ocean. The only way water leaves is through evaporation, which concentrates the dissolved salts and minerals, resulting in its high salinity. The other options are freshwater lakes with natural outflows.
