Which of the following is an advantage of ex situ conservation over in situ conservation, in the context of biodiversity conservation?

The ex situ conservation is the conservation of biodiversity outside of its natural habitat. It protects endangered species from external threats like predation and poaching. However, it is more expensive. In situ conservation (e.g., biosphere reserve) offer protection to the entire ecosystem (both the threatened animal and its habitat). Species can adapt to changing environment in in situ conservation.
