The correct option is C Western Ghats and Eastern Himalayas
Tropical rain forests occur over equatorial or sub equatorial regions with abundant warmth and rainfall (200-350 cms/ year) almost throughout the year. The forests are impenetrable with maximum diversity. Productivity is also maximum. Almost 200 different types of tall trees are expected in one hectare, which is maximum as compared to other forest types. Standing crop biomass is highest. Soil is highly leached due to heavy rains and is therefore poor in nutrients. Large quantity of nutrients remain locked in vegetation. In India, these forests are common in Western Ghats, some parts of Eastern Himalayas, e.g., Assam region and Andamans.
