Explanation
The correct option is:
(D) Hooghly.
Hooghly is not a tributary of the River Ganga. The Hooghly River, also known as the Bhagirathi-Hooghly, is a distributary of the Ganga. It branches off from the main course of the Ganga near the city of Kolkata (Calcutta) in West Bengal, India. The Hooghly River flows southward and eventually merges with the Bay of Bengal. While the Hooghly is an important river in its own right, it is not considered a tributary of the Ganga as it is a distributary.
