Which analysis is correct while linking Hooghly with the Ganga system?

Correct answer: It is a distributary stream linked with the Ganga delta region

The direct answer is A: Hooghly is a distributary connected with the delta region of the Ganga system. A river system may divide into branches in its lower course when it approaches a flat coast and the sea. These branches carry water and sediment toward different parts of the delta. Hooghly is an important branch of the Ganga in West Bengal. Thus option A is correct. Option B is wrong because Hooghly does not belong to the Indus system and is not a Himalayan tributary of the Indus. Option C is wrong because a rift valley is a landform, not a river identity, and Hooghly is not the Narmada’s rift valley. Option D is wrong because Hooghly has no connection with the upper course of the Kaveri, which is a separate peninsular river. Remember the direction: a tributary enters a main river, whereas a distributary leaves it. Since Hooghly branches from the Ganga in the deltaic lower course, the correct description is option A. Exam cue: Ganga delta branch in West Bengal means Hooghly.
