The correct option is B Zoological parks

Ex situ conservation

• Ex situ (off site) conservation is the approach of conserving species by taking them out from their natural habitats and then keeping them in a special setup under human care.
• Zoological, botanical and wildlife sanctuary parks, in vitro fertilisation, cryopreservation, seed bank and tissue culture belong to this approach of conservation.

Wildlife Sanctuary
Wildlife sanctuaries are the legally conserved areas where animal species and their habitats are protected from outside disturbances. Wildlife sanctuaries are thus a method of conserving biodiversity using the in situ approach.

Biosphere reserves
Biosphere reserves include terrestrial, marine and coastal ecosystems that are nominated by the national government but remain under the jurisdiction of the state where they are located. This belongs to the in situ approach of conservation where the species is conserved in its natural habitat.

National parks
National parks are the areas that serve the purpose of conservation of biodiversity present in that particular area and are protected by the government. This belongs to the in situ approach of conservation where the species is conserved in its natural habitat.

Zoological parks
Zoological parks are places where animals are kept inside enclosures to be taken care by humans. This is a method of ex situ conservation.
