Question 15.

Option D is the correct answer. 

The 'exclosures' are mentioned as fenced areas cleared of invasive rabbits and feral cats. The term "exclosures" points to the intentional exclusion of these invasive species to create a safe environment for the bandicoots and other native animals.

Option A: While the bandicoots help in restoring the cattle damaged landscape, the term 'exclosure' does not relate to it.

Option B: The exclosures are cleared of feral cats, but the passage does not mention removing large bilbies, which are actually part of the controlled environment.  The exclosures themselves are specifically to protect the bandicoots from cats and rabbits, not bilbies.

Option C: The exclosures are not about making an area entirely predator-free for all species. Instead, the purpose is to create controlled environments where invasive species like rabbits and feral cats are removed. Predators are still present in the Wild Training Zone, where bandicoots and other marsupials learn to coexist and evade predators.
