The correct answer is C. Edakkal.
Edakkal Caves are a group of two rock-cut caves located in the Edakkal hills near the village of Edakkal in Wayanad district of Kerala, India. The caves are known for their prehistoric rock paintings and inscriptions. The paintings are believed to have been made by the Mesolithic people who inhabited the area around 6,000 years ago. The inscriptions are in the Brahmi script and are believed to have been made by the early Aryan settlers of the area.
The caves are located at an altitude of 1,500 meters (4,900 feet) above sea level. The main cave is about 10 meters (33 feet) long and 5 meters (16 feet) wide. The second cave is smaller and is located about 100 meters (330 feet) from the main cave.
The paintings in the caves depict a variety of animals, including elephants, tigers, deer, and birds. The paintings also depict human figures, some of which are engaged in hunting or other activities. The inscriptions in the caves are mostly religious in nature and are dedicated to various Hindu gods and goddesses.
