Dhaka, the capital of Bangladesh, is situated on the Buriganga River, which is a distributary of the Padma River (the Bengali name for the lower Ganges). The Padma is the major river flowing through Bangladesh and is often cited as the main river near Dhaka. While the Brahmaputra, Ganga, and Meghna (Option C) are all major rivers in Bangladesh, the Padma is most closely associated with Dhaka's location.
