As of 2014, which one of the following is included in the World List of Biosphere Reserves by UNESCO?

The correct choice is: “Sunderbans”

The Sunderbans Biosphere Reserve in West Bengal was added to UNESCO’s World Network of Biosphere Reserves (the Man and the Biosphere programme) in 2001. It was one of the first Indian reserves on the list, after the Nilgiri (2000) and Gulf of Mannar (2001) reserves.

“Nallamalai Hills” (Andhra Pradesh) hold a tiger reserve but are not a UNESCO biosphere reserve. The Cold Desert Biosphere Reserve in Himachal Pradesh, which covers the “Spiti Valley” area, was added to the UNESCO list only in 2020. In 2014 neither it nor the “Kinnaur Region” was on the list.
