Correct Answer: Option (B) — It is a confluence of different biogeographical zones

Concept & Option Breakdown

Standard Reference Verified

This confluence of distinct biogeographical zones, coupled with steep altitudinal variations, creates a wide variety of ecological niches and high species diversity and endemism.
