B
They provide the natural habitat for wild life
C

D

Detailed Solution
Botanical gardens maintain living collections of a large number of plant species, including rare and threatened plants, outside their natural habitats.
This is ex-situ (off-site) conservation of plant germplasm.
Botanical gardens also help in the identification of plants, in research and in education.
They do not provide the natural habitat for wildlife; that is the role of national parks and sanctuaries (in-situ conservation).
Recreation and the display of tropical plants are only minor functions.
