Indo-Burma is a biodiversity hotspot. Ecological hot spots are large areas of Earth's land surface which have high concentrations of plant endemism and also experience high rates of habitat loss. In India, 4 ecological hot spots are presently identified. The Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland constitute the 4 biodiversity hotspots in our country. One of the major features of these places is the presence of numerous endemic species.
So, the correct answer is 'Indo-Burma is not a biodiversity hotspot'.
