Consider the following pairs : Wetlands Confluence of rivers 1. Harike Wetlands : Confluence of Beas and Satluj/Sutlej 2. Keoladeo Ghana National Park : Confluence of Banas and Chambal 3. Kolleru Lake : Confluence of Musi and Krishna Which of the above pairs is/are correctly matched?

Let's evaluate each pair of wetlands and their associated river confluences: **Harike Wetlands : Confluence of Beas and Satluj/Sutlej**: This pair is **correctly matched**. Harike Wetland, located in Punjab, India, is a significant wetland ecosystem formed at the confluence of the Beas and Sutlej rivers. It is also a designated Ramsar site. **Keoladeo Ghana National Park : Confluence of Banas and Chambal**: This pair is **incorrectly matched**. Keoladeo Ghana National Park (formerly Bharatpur Bird Sanctuary) is a famous wetland in Rajasthan. While the Chambal River is a major river in the region, Keoladeo receives its water primarily from the Gambhir and Banganga rivers, not the direct confluence of Banas and Chambal. The Banas itself is a tributary of the Chambal, but their confluence is elsewhere. **Kolleru Lake : Confluence of Musi and Krishna**: This pair is **incorrectly matched**. Kolleru Lake is a large freshwater lake in Andhra Pradesh, situated between the deltas of the Godavari and Krishna rivers. It acts as a natural flood-balancing reservoir for these two major rivers. The Musi River is a tributary of the Krishna, but Kolleru Lake is not at their confluence. Therefore, only pair 1 is correctly matched.
