Which two rivers meet to form the Hooghly River?

Strictly speaking, Hooghly is an estuary of the Ganga. Option A (“Ganga and Yamuna”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option B (“Ganga and Damodar”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. Option D (“Bhagirathi and Jalangi”) is incorrect because it does not match the river basin, lake type, location, tributary relationship, project or hydrological feature specified in the question. The key concept is to match the water body with its basin, type, location and defining feature. Therefore the correct option, index and explanation consistently identify Ganga branches only. The Hooghly River is actually a distributary (branch) of the Ganga. At Farakka Barrage in West Bengal, the Ganga splits into two: the main stream continues as Padma River (flowing into Bangladesh) and the western branch becomes the Bhagirathi-Hooghly.
