Keibul Lamjao National Park is located in which lake?

1. A

   Loktak

   Loktak Lake. This option correctly claims that Keibul Lamjao National Park is situated on the Loktak Lake in Manipur, as it is famously known as the world's only floating national park famous for the endangered Sangai deer.

2. B

   Dal

   Dal Lake. This option claims the national park is in Dal Lake, which is incorrect because Dal Lake is located in Srinagar, Jammu and Kashmir, and lacks the floating phumdis characteristic of Keibul Lamjao.

3. C

   Wular

   Wular Lake. This option claims the park is located in Wular Lake, which is incorrect as Wular is one of the largest freshwater lakes in India situated in Bandipora district of Jammu and Kashmir.

4. D

   Kolleru

   Kolleru Lake. This option claims the park is located in Kolleru Lake, which is incorrect because Kolleru is a large freshwater lake situated in the state of Andhra Pradesh.

Summary. Official key is (a) Loktak. Keibul Lamjao National Park is situated in the northeastern state of Manipur and forms an integral part of the Loktak Lake ecosystem. It is globally renowned as the last natural refuge of the endangered brow-antlered deer, or Sangai. Candidates often confuse freshwater lakes across India, but the unique floating biomass known as phumdis exclusively links this park to Loktak. Therefore, only option (a) correctly identifies the lake.
