Which one of the following is a tributary of Barak River in Manipur?

The Barak River originates in the Manipur Hills near Mt. Japov in Nagaland and flows through Manipur, Mizoram, and Assam before entering Bangladesh [2]. The principal tributaries of the Barak River include the Dhaleswari, Jiri, Singla, Longai, Sonai, and Katakhal. The Dhaleswari is a significant affluent that drains parts of the Barak basin [2]. In contrast, the other options provided are tributaries of the Brahmaputra River system. The Subansiri is a major right-bank tributary of the Brahmaputra originating in Tibet [1]. The Dhansiri (South) is a left-bank tributary of the Brahmaputra flowing through Nagaland and Assam [1]. The Manas River is also a major right-bank tributary of the Brahmaputra, originating in Bhutan [2]. Therefore, Dhaleswari is the only river among the choices that belongs to the Barak river system.
