The high biodiversity in Western Ghats is linked with which combined physical effect?

Altitude, moisture, and varied habitats

The governing concept is the relationship between relief, climate, and habitat diversity. The Western Ghats rise sharply from the coastal plains, causing moist monsoon winds to ascend and produce substantial orographic rainfall on their windward slopes. Differences in altitude, slope, exposure, temperature, rainfall, soil, and drainage then create many ecological niches over a relatively short distance. These varied habitats support exceptionally rich plant and animal life, making the region a recognized biodiversity hotspot. Therefore, option C is correct. Sandy plains alone cannot explain the range of habitats, and the Western Ghats are not covered by glaciers. Coral reefs are marine formations and do not form on ordinary mountain slopes. The combined effects of elevation and moisture are the decisive physical explanation.
