IASCODEX · Accepted Answer

Correct Option: D. saline lakes

Strategy: Identify the region and the nature of the places. Didwana and Kuchaman are strongly associated with Rajasthan, where saline lakes are prominent due to arid geography. Terms like glacier or mangrove do not fit Rajasthan's climatic context, nor are these places listed as Ramsar sites.

Key Info: Didwana, Kuchaman, Sargol, and Khatu are all sites located in Rajasthan, India, notable for their saline lakes.

**Site-Specific Details**
- **Didwana Lake** is a prominent saline lake in Nagaur district, Rajasthan. The region is known for salt extraction and has historical significance, with Didwana town situated near the lake.
- **Kuchaman** is famous for **Kuchaman Lake**, another saline body within Nagaur district, extending over approximately 8.5 sq km. The Kuchaman area is also recognized for its fort and heritage sites.
- **Sargol** and **Khatu**: Both places are associated with local saline water bodies. Khatu (often referred to as Khatu Shyamji) is better known for its temple, but also contains a smaller saline lake in Sikar district.

**Regional Context**
- Rajasthan's saline lakes form due to internal drainage in the arid region and high evaporation rates. Other major examples include the Sambhar and Pachpadra lakes. Saline lakes are critical for salt production in India.
- These locations are not glaciers (predominantly found in the Himalayas), mangrove areas (such as Sundarbans), or designated Ramsar sites under the Wetlands Convention.
- Saline lakes of Rajasthan contribute ecologically and economically (especially in traditional salt-making) and offer important habitats for migratory birds in winter.
