Correct answer
Explanation
The Sundarbans delta is formed by the confluence of the Ganges and Brahmaputra river systems (with the Meghna river) in Bangladesh. The Ganges brings sediment from the Himalayas, while the Brahmaputra contributes massive water and sediment flow. Together they create the world's largest mangrove ecosystem. The Indus is in Pakistan, while Yamuna is a tributary of the Ganges.
