A geographer is studying a region in the northern plains of India characterized by fine alluvial deposits, high fertility, a marshy and waterlogged environment, and a historical presence of dense forests. This region is typically found immediately south of the Bhabar belt. Which physiographic division does this description best fit?

Accepted Answer

B. The Terai belt — The description accurately defines the Terai belt.
