The combined delta of Ganga and Brahmaputra is famous for which vegetation?

Correct answer: Mangrove forests

Direct answer: Option A, mangrove forests, is correct. The Ganga and Brahmaputra deposit enormous amounts of sediment and form a vast delta at the head of the Bay of Bengal. Its tidal, muddy, saline, and frequently waterlogged environment supports mangroves. The best-known part is the Sundarbans, famous for dense mangrove vegetation and tidal channels. Option A therefore matches both the delta environment and the famous vegetation. Option B, cactus forests, are associated with dry desert or semi-desert conditions, not tidal delta wetlands. Option C, deodar forests, are mountain conifer forests found in high Himalayan areas. Option D, grass deserts, is not the characteristic vegetation of this humid, tidal delta. Memory cue: Sundarbans means Ganga–Brahmaputra delta and mangroves.
