Which lake is counted among India's high-altitude large saline lakes?

Correct answer: Pangong Tso

The correct answer is Pangong Tso. It is a large, high-altitude endorheic lake in the Ladakh region and contains saline water, although the salinity can vary in different parts of the lake. Because it has no ordinary outlet to the sea, dissolved minerals accumulate in its basin. Dal Lake, Bhimtal and Nainital are important Himalayan lakes, but they are freshwater lakes associated with different local drainage and tourism settings. Thus option A is the only choice that satisfies both clues: high altitude and saline character. The governing concept is the classification of lakes by altitude, water chemistry and drainage. Remembering Pangong Tso as a saline Himalayan border-region lake helps distinguish it from the freshwater lakes of Kashmir and Uttarakhand.
