Match List-I with List-II and select the correct answer using the code given below the Lists : List-I (Lake) A. Ashtaniudi Kayal B. Himayat Sagar C. Dal Lake D. Tsomgo Lake List-II (Type) 1. Residual (sweet water) 2. Lagoon 3. Glacial 4. Artificial (sweet water) Code :

The classification of Indian lakes is based on their origin and characteristics. Ashtamudi Kayal in Kerala is a prominent lagoon and backwater system formed by coastal processes [3]. Himayat Sagar is an artificial freshwater lake in Hyderabad, created in 1920 by damming the Musi River to provide drinking water . Dal Lake in Srinagar is categorized as a residual freshwater lake, often associated with the floodplains of the Jhelum River and tectonic origins in the Himalayan region [2]. Tsomgo Lake (also known as Changu Lake) in Sikkim is a high-altitude glacial lake, formed by the melting of glaciers [2]. Matching these characteristics: A-2 (Lagoon), B-4 (Artificial), C-1 (Residual), and D-3 (Glacial) leads to the sequence 2-4-1-3.
