Which of the following mountain passes in the Western Ghats facilitated ancient trade and cultural contact between the Chera country and the Tamil plains of Kongunadu?

💡 Solution & Explanation

The Palakkad Gap is a prominent low-altitude mountain pass in the Western Ghats that cuts through the mountains to connect the coastal plains of Kerala with the interior plateau of Tamil Nadu. Other options like the Thamarassery Churam are mountain passes located further north within Kerala connecting to Wayanad rather than serving as the primary inter-state lowland corridor. This geographical break has historically facilitated trade migrations, botanical exchanges, and climatic interactions across the southern peninsula.
