Forest Types and Regional Distribution

South-West Bengal, particularly the Sundarbans region and surrounding areas, has a unique combination of mangrove forests (in the coastal delta region), evergreen forests (in the wetter areas), and deciduous forests. This region experiences diverse climatic and soil conditions that support multiple forest types. North Coastal Andhra Pradesh primarily has deciduous forests with some mangroves but lacks significant evergreen forests. Southern Saurashtra has thorn scrub and dry deciduous forests but lacks mangroves and significant evergreen forests. Andaman and Nicobar Islands have tropical evergreen and semi-evergreen forests but limited mangrove and deciduous forest combinations. South-West Bengal's geographical and climatic diversity makes it unique in supporting all three forest types. > South-West Bengal = Sundarbans + diverse forest types. Mangrove + Evergreen + Deciduous. Answer: b.
