Which one of the following rivers does not originate in India ?

Among the four rivers, the Sutlej alone has its headwaters outside present-day India: it rises from the Manasarovar–Rakas (Rakshastal) lakes on the Tibetan plateau (near Mount Kailash) and then enters India, so its source lies in Tibet/China [1]. By contrast, the Beas originates from Beas Kund near the Rohtang Pass in Himachal Pradesh [2]; the Ravi rises west of Rohtang in the Kullu/Chamba region of Himachal Pradesh [2]; and the Chenab is formed by the Chandra and Bhaga streams in the Lahaul/Bara-Lacha Pass area of Himachal Pradesh before flowing westward [3]. Therefore the river that does not originate in India is Sutlej (option 4).
