The correct sequence of the eastward flowing rivers of the peninsular India from north to south is

The correct north-to-south sequence of major east‑flowing peninsular rivers places Subarnarekha furthest north, followed by the Mahanadi, then the Godavari, Krishna, Pennar, Cauvery and finally the Vaigai (Vagai). Authoritative summaries and north-to-south lists of east‑flowing peninsular rivers enumerate Subarnarekha first and then Mahanadi, Godavari, Krishna, Pennar, Kaveri and Vaigai in that order. Textbook descriptions also emphasise the relative positions of Mahanadi and Godavari among peninsular rivers, supporting their placement north and south respectively in the sequence [1]. Thus option 1 matches the correct geographic ordering from north to south.
