Detailed Solution:
The correct answer is “Botenical garden”.
Botanical garden is NOT an example of in-situ conservation strategy. In-situ conservation involves protecting species in their natural habitat.
Biosphere reserves, National Parks, and Sacred groves are all examples of in-situ conservation, as they protect species in their natural environments.
Botanical gardens are examples of ex-situ conservation, where species are conserved outside their natural habitat. They are artificial environments where plants are cultivated and preserved.
