India is home to four major biodiversity hotspots recognised globally: the Himalayas, the Western Ghats, the Indo-Burma region, and the Sundaland (which includes the Nicobar Islands). Among the options provided, the Western Ghats is internationally recognised as one of the world's eight "hottest hot spots" of biological diversity. It is known for its high levels of species richness and endemism (species found only in that region).
