    Correct Answer: B

    Solution :

    [b] Tropical Moist Evergreen Forests These are climatic climax forests found commonly in areas having annual rainfall above 250 cm and temperature\[25-30{}^\circ \,\,C\]. These forests are chiefly distributed on the Western face of Western Ghats, Asom, Cachar, parts of West Bengal, Northern Canara, Annamalai hills and Coorg in Mysore and Andaman Islands. Tropical Moist Deciduous Forests These forests are found in the area having temperature of \[25-30{}^\circ \,\,C\] and quite high annual rainfall of 150-200 cm spread over most of the year, but periods of rain alternating with very short periods of dryness. Tropical Moist Semi-Evergreen Forests These are also climatic climax forests found commonly in areas of annual rainfall 200-250 cm and temperature\[25-32{}^\circ \,\,C\]. These forests are chiefly distributed along the Western Ghats, in upper parts of Asom, Odisha and in Andaman Islands. These forests are more developed in the Northern India than in Southern India.
