The type of conservation in which the threatened species are taken out from their natural habitat and placed in special setting where they can be protected and given special care is called

The correct option is Biodiversity conservation.

Let us understand the concept step-by-step:
1. Biodiversity Conservation: This refers to the protection, preservation, and management of ecosystems and habitats to ensure that different species can survive and thrive. It is broadly categorized into two types: in-situ (on-site) conservation and ex-situ (off-site) conservation.
2. In-situ Conservation: This is the conservation of genetic resources and endangered species within their natural ecosystems and habitats (for example, in national parks, wildlife sanctuaries, and biosphere reserves).
3. Ex-situ Conservation: This involves removing threatened, endangered, or rare species from their vulnerable natural habitats and transferring them to specialized, human-managed settings. In these settings, such as zoological parks, botanical gardens, safari parks, and seed banks, they can be protected from predators and environmental pressures, and given specialized care and breeding opportunities.
Because the process described in the question involves taking threatened species out of their natural habitats and placing them in protective, specialized environments, it is specifically referred to as ex-situ conservation, which is a major approach under the umbrella of Biodiversity conservation.
