'Majuli' the river island, is located in which one of the following rivers?

Majuli is a prominent river island located in the Brahmaputra River in the state of Assam, India [4]. It is formed due to the low gradient of the river, which leads to a highly braided channel with numerous islands and sandy shoals [2]. Majuli is bounded by the Lakhimpur District to the north and the Jorhat District to the south [2]. It is recognized as the largest river island in India and is often cited as the largest inhabited riverine island in the world [4]. The island is formed by the main Brahmaputra channel to the south and the Kherkutia Xuti (an anabranch of the Brahmaputra) to the north [5]. Due to heavy silt loads and the turbulent nature of the river during the rainy season, the region faces significant instability and annual inundation [5].
