Travelling from north to south, which one of the following is the correct sequence of the given mountain ranges ?

The correct sequence from north to south is Vindhya range, Satpura range, Ajanta range, and Palghat range. The Vindhya Range lies in Central India and acts as a traditional boundary between North and South India [t3]. Immediately south of the Vindhyas is the Narmada River valley, followed by the Satpura Range, which runs parallel to the Vindhyas [t2][t3]. Further south, in the state of Maharashtra and south of the Tapi River, lies the Ajanta Range [t4][t5]. Finally, the Palghat Gap (or Palghat range area) is located much further south in the Western Ghats, specifically between the Nilgiri Hills to the north and the Anaimalai Hills to the south, near the border of Kerala and Tamil Nadu [t4][t5]. This geographical progression confirms that the Vindhyas are the northernmost and Palghat is the southernmost among the given options.
