Solution

The correct option is B Western ghats
Hot-spot are areas with high density of biodiversity which are also the most threatened ones. Hot spots are determined by four factors, 
(i) Number of species/species diversity, 
(ii) Degree of endemism, 
(iii) Degree of threat to habitat due to its degradation and fragmentation 
(iv) Degree of exploitation. India has two hotspots -North-East Himalayas and Western Ghats. 
Western Ghats occur along the western cost of India for a distance of about 1600 km in Maharashtra, Karnataka, Tamil Nadu and Kerala extending over to Sri lanka.
Therefore, the correct answer is option B.
