The correct answer is B) 2-1-3-4.
The question asks for the order of the given tributaries of the River Ganga from east to west. When considering the major north-bank tributaries joining the Ganga in the plains, their approximate order from East to West is: Kosi (joins near Kursela, Bihar) -> Gandak (joins near Patna, Bihar) -> Ghaghara (joins near Chapra, Bihar) -> Gomti (joins near Ghazipur, Uttar Pradesh, which is west of the major confluence points of Kosi, Gandak, and Ghaghara).
The list provided includes four prominent left-bank (north bank) tributaries of the Ganga. Their confluence points with the Ganga are located in different parts of Bihar and Eastern Uttar Pradesh, determining their relative east-west positions. Kosi is the easternmost among the options, followed by Gandak, then Ghaghara, and finally Gomti to the west.
