Which of the following National Parks is unique in being a swamp with floating vegetation that supports a rich biodiversity?

Answer b.

Explanation Answer · b

Option (b) Keibul Lamjao National Park. It is the world's only floating national park, made of phumdis — mats of decomposed floating vegetation — on Loktak Lake in Manipur. Keibul Lamjao lies on the south-eastern rim of Loktak Lake, Manipur, and its terrain is largely phumdi: heterogeneous masses of soil, vegetation and organic matter in various stages of decay that float on the water and thicken enough to bear the weight of a deer. It was notified a sanctuary in 1966 and a national park in 1977, specifically to save the sangai or Manipur brow-antlered deer (Rucervus eldii eldii), which walks on phumdi and is found nowhere else in the wild. Loktak is also a Ramsar site (1990) and was placed on the Montreux Record in 1993. No other Indian national park is a floating swamp of this kind.
