Which river system forms the world's largest river delta (the Sundarbans delta) as it enters the Bay of Bengal?

Answer and explanation

Correct answer: C. Ganges-Brahmaputra-Meghna

  1. Step 1: The Ganges and Brahmaputra rivers merge in Bangladesh to form the Padma and Jamuna, and subsequently the Meghna.
  2. Step 2: This enormous sediment discharge creates the Ganges-Brahmaputra Delta (Bengal Delta), spanning over 100,000 square kilometers, famous for the Sundarbans mangrove forest.
Answer
Ganges-Brahmaputra-Meghna
Why not the others: 'Mekong Delta' in southern Vietnam is smaller; 'Mississippi Delta' is an active bird-foot delta in Louisiana; 'Nile Delta' is an arcuate delta in northern Egypt.
