If you want to see gharials in their natural habitat, which one of the following is the best place to visit?

1. Gharials (Gavialis gangeticus) are a critically endangered crocodilian species found primarily in clean river systems with sandy banks. 2. The Chambal River, particularly the National Chambal Sanctuary spanning parts of Rajasthan, Madhya Pradesh, and Uttar Pradesh, harbors the largest known population of gharials in their natural habitat. It is considered the best place to visit to see them. 3. Bhitarkanika Mangroves in Odisha is famous for its large population of Saltwater Crocodiles, not gharials. 4. Pulicat Lake is a brackish water lagoon and not a typical habitat for gharials. 5. Deepor Beel in Assam is a freshwater lake (wetland) known for its birdlife, but not a primary gharial habitat. 6. Therefore, the Chambal River is the most appropriate answer.
