None of the statements given above are correct. Amarkantak Hills, for instance, are located at the junction of the Vindhya and the Maikala Ranges, not the Sahyadri Ranges. The Biligirirangan Hills are not a part of the Satpura Range but are rather located at the edge of the Western Ghats, and the Seshachalam Hills are also part of the Eastern Ghats, not the Western Ghats. Understanding the geographical relationships and classifications of these hills is crucial for the UPSC Prelims, as accurate knowledge of Indian geography is often tested through various contexts.
