Explanation:

Both statements are incorrect.

• A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.

To qualify as a biodiversity hotspot, a region must meet two strict criteria:

• It must have at least 1,500 vascular plants as endemics— which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable.

• It must have 30% or less of its original natural vegetation. In other words, it must be threatened.

Around the world, 36 areas qualify as hotspots.

• India hosts 4 biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-?Burma region and the Sundaland (Includes Nicobar group of Islands).

Hence option 4th is correct.
