Which of the following options correctly matches the conservation methods with their appropriate pairs?

  In-situ conservation/National park

  Ex-situ conservation/Botanical garden

The correct option is:

(a)    In situ conservation/National park  ,Ex situ conservation/Botanical garden

In situ, conservation refers to the conservation of species within their natural habitats, and one of the methods used for this is by establishing national parks, where human activities are limited to preserve the natural environment and wildlife.

Ex-situ conservation, on the other hand, involves conserving threatened species outside their natural habitats. Botanical gardens serve as facilities for ex-situ conservation, where plants are cultivated and protected in controlled environments, away from their original habitats.

The other options (b), (c), and (d) do not correctly match the conservation methods with their respective pairs. Cryopreservation and tissue culture are techniques used in ex-situ conservation, but they are not correctly matched with the provided options. Wildlife sanctuaries and seed banks are in-situ and ex-situ conservation methods, but they are not paired correctly in option (b) and (c) respectively. Sacred groves are associated with in situ conservation, but they are not properly paired in option (d).
