• C. $X$ - Endemic; $Y$ - Exotic; $Z$ - Endangered
• D. $X$ - Epidemic; $Y$ - Exotic; $Z$ - Endangered

Answer 1

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

Endemic species are those species that are found only in particular area i.e., Indian giant squirrel. Species that have been introduced, or moved, by human activities to a location where they do not naturally occur are termed exotic. Exotic species are not necessarily harmful.
A species at risk of extinction because of human activity, changes in climate, changes in predator-prey ratios, etc. is called as an endangered species.

Thus, the correct answer is option C.
