Answer: 
The Western and the Eastern Ghats flank either side of the "central Deccan plateau". 
Step-by-step explanation: 
- The Deccan Plateau was formed by the end of the Cretacious period about "66 million years ago". 
- When the "Indian plate" was moving from above the "Reunion Hotspot", the volcanic eruptions from the hotspot resulted in the formation of the Deccan Plateau. 
- The "western edge" of the "Deccan Plateau" is characterized by the "presence of the Western Ghats" and the eastern edge by the presence of the Eastern Ghats.
