Explanation:

• Edakkal Caves are located in Wayanad district of Kerala. The name ‘Edakkal’ literally means ‘a stone in between’.
• The caves are situated 1,200 m (3,900 ft) above sea level on Ambukuthi Mala, on the Mysore Plateau, in the Western Ghats.
• The Edakkal caves are believed to be camping shelters of the Neolithic community (the south Indian Neolithic culture zone).
• Edakkal is the only known place in India with Stone Age carvings. Edakkal caves are famous for its pictorial paintings (cave paintings), which are considered to be of 6000 B C. The human figures of these caves have raised hair and some have masks.
• In the wake of Western Ghats being declared a World Heritage Site by UNESCO, archaeologists and historians are now emphasising on the significance of Edakkal Caves in Wayanad and the fact that the location fulfils all the criteria that can qualify it as a World Heritage Site. Which means it is still under trail. Hence statement 3rd is incorrect.
