Explanation
The Brahmaputra river system features several major tributaries that join it as it flows from east to west through the Assam valley. The Tista (Teesta) is the westernmost right-bank tributary, rising from Kanchenjunga and joining the Brahmaputra in Bangladesh [4]. Moving eastward, the Subansiri is a major right-bank tributary originating in Tibet that joins the river in the Assam valley [4]. Further east, near the entry point of the river into India in Arunachal Pradesh, the Dibang and Lohit rivers join the main stream [3]. Specifically, the Dibang meets the Dihang (main stream) slightly west of the Lohit confluence near Sadiya [1]. Therefore, the correct west-to-east sequence is Tista (4), Subansiri (3), Dibang (2), and Lohit (1), which corresponds to the order 4-3-2-1.
