The question is based on geographical knowledge of Indian rivers and their location on the map. As per their locations, the right answer is option 2.

In Option 1, it says rivers are Kosi, Gomati, Ghaghara, and Gandak. This is incorrect because while Kosi is correct for river 1, Gomati isn`t the river for 2.

Option 2 lists the rivers as Kosi, Ganga, Gomati and Ghaghara which matches their respective labels on the map correctly.

Option 3 says the rivers are Gandak, Ganga, Gomati, and Ghaghara. This is wrong as Gandak isn`t river 1.

Lastly, in Option 4, Teesta, Gomati, Ghaghara, and Kosi are mentioned. This isn`t correct as Teesta isn`t river 1 and Kosi isn`t river 4.

So, the appropriate answer to the question is indeed option 2.
