The correct option is (c) 1 and 3 only.
Explanation
Lakes in India are classified based on their mode of formation (tectonic, glacial, volcanic, aeolian, or marine) and the nature of their water (freshwater or saltwater). The physiography of the region largely dictates these characteristics.
Statement 1 is Correct:
Wular Lake in Jammu and Kashmir is the largest freshwater lake in India. Unlike most Himalayan lakes which are of glacial origin, the Wular Lake basin was formed as a result of tectonic activity. It is fed by the Jhelum River.
Statement 2 is Incorrect:
The Sambhar Lake in Rajasthan is India's largest inland saltwater (saline) lake, not a freshwater lake. It is an ephemeral lake situated in the arid region of the Indian Desert and is a major source of salt production in India.
Statement 3 is Correct:
Most of the freshwater lakes in the Himalayan region are of glacial origin. These lakes were formed when glaciers excavated basins that were later filled with snowmelt and precipitation. Examples include the Dal Lake, Bhimtal, Nainital, and Loktak Lake.
Key Takeaway:
Wular Lake is a unique freshwater lake formed by tectonic activity, whereas Sambhar Lake is a saline lake in the desert. Most other Himalayan lakes are glacial in origin.
