Solution

The correct option is C X – Endemic; Y – Exotic; Z - Endangered

Endemic species are plants and animals found exclusively in a particular area. As Indian giant squirrel is found only in India, so X here is endemic species.

Non-native species found in areas outside natural habitat are called exotic species. As Eicchornia is not naturally found in India, so Y here is exotic species.

Species of plants and animals that are on the verge of extinction are called endangered species, Indian rhinoceros will no longer be seen on earth if not conserved, so Z here is endangered species.
