Farakka
Explanation
The River Ganga flows generally southeastwards through the plains of northern and eastern India. Upon reaching West Bengal, the river reaches the apex of its delta, where the flow separates into distinct channels.Detailed Analysis:
- Allahabad Allahabad (Prayagraj): Incorrect. This location marks the confluence (Sangam) of the River Ganga with its largest tributary, the Yamuna, and the mythical Saraswati. It is a point of joining, not bifurcation.
- Farakka Farakka: Correct. Located in the Murshidabad district of West Bengal, Farakka is the site where the Ganga bifurcates.
- The Bhagirathi-Hooghly (a distributary) flows southwards through the deltaic plains to the Bay of Bengal.
- The main stream continues southeastwards into Bangladesh, where it is known as the Padma.
- Haridwar Haridwar: Incorrect. Haridwar is the location where the Ganga emerges from the mountains and enters the plains.
- Ambala Ambala: Incorrect. Ambala is located on the water divide between the Indus and the Ganga river systems. It is not a location on the course of the Ganga where bifurcation occurs.
Key Takeaway: Farakka is the strategic point where the Ganga splits into its distributary, the Bhagirathi-Hooghly (serving Kolkata), and the main channel, the Padma (flowing into Bangladesh).
