Which among the following is not correctly matched?
A. Dampa sanctuary- Mizoram
B. Valmiki reserve- Bihar
C. Rohla national park- Himachal Pradesh
D. Gandhi Sagar sanctuary- Rajasthan

Hint: In order to preserve the precious biodiversity of our country, we have set up several biosphere reserves, national parks, and wildlife sanctuaries. These are part of in- situ conservation techniques for protecting biodiversity.

Step by step answer:Biodiversity rich regions are protected in-order to prevent biodiversity destruction which leads to harmful effects. There are 14 biosphere reserves in India for this. Also, we have 90 national parks and 448 wildlife sanctuaries to ensure that all species are protected and are safe from extinction by giving emphasis to endangered species.
-Dampa wildlife sanctuary is a tiger reserve in Mizoram.
-Valmiki reserve is also a wildlife sanctuary in Bihar that ensures the protection of tigers.
-Rohla national park is present in the state of Himachal Pradesh. It is one of the 14 national parks in India.
-Gandhi Sagar wildlife sanctuary is present in Madhya Pradesh.
Apart from in- situ conservation of the biosphere, there are several ex-situ conservation techniques. They include zoological parks, botanical gardens, and wildlife sanctuaries. The advancement in technology is able to conserve biodiversity in a more efficient manner. It is done through techniques like tissue culture, cryopreservation, seed banks, etc. Using cryopreservation techniques, we can preserve gametes of endangered species in a viable manner and thereby prevent the species from extinction.
Hence the correct option is D

Note: Biodiversity hotspots are the regions where species diversity and the number of endemic species are very high. They are protected so that we can decrease the rate of extinction of species by 30%. Examples are the eastern Himalayas and western ghats.
