Answer : 4. "Telangana"
Explanation :

Recently, Mesolithic rock paintings were unearthed at Seetamma Loddhi, Gattusingaram in Peddapalli district of Telangana. Discovered on a hill in a dense forest, the paintings adorn a 1,000-foot-long, 50-foot-high sandstone rock shelter. The Mesolithic or Middle Stone Age spanned the gap between the Palaeolithic and Neolithic periods, spanning approximately 12,000–10,000 years ago. Notable for the transition from large chipped stone tools to smaller tools attached to bone or wooden handles to create tools such as microliths, saws and sickles, it marked an important era in human cultural evolution.
