Which of the following geomorphological processes best explains the formation of the Majuli riverine island in the Brahmaputra River?

Options:

• A: It is a tectonic upliftment zone in the middle of the Assam valley that diverted the Subansiri river.
• B: It is formed solely by the depositional work of the Lohit and Dibang rivers before they meet the main stream.
• C: It is formed due to the bifurcation of the Brahmaputra into the Kherkutia Suti and the main Brahmaputra channel, combined with high sediment load and low gradient.
• D: It is an estuarine island formed due to tidal backwaters of the Bay of Bengal reaching up to Upper Assam.
