Verified by Toppr

The correct option is C Exclusively found in a zone
Endemic means a species which is native to a place and is not found anywhere else in the world. Endemic basically means indigenous. The more endemic species at a place more is the biodiversity of that place. For example, the Nilgiri tahr also known as Nilgiri Ibex is endemic to the Nilgiri Hills and some part of Western Ghats of Kerala.
So, the correct answer is 'Exclusively found in a zone'.
