Detailed Solution:
The correct answer is “Kharvela”.
The Hathigumpha Inscription ("Elephant Cave" inscription), from Udayagiri, near Bhubaneswar in Odisha, was inscribed by Kharavela, the then Emperor of Kalinga in India, during 2nd century BC.
The Hathigumpha Inscription consists of seventeen lines in a Central-Western form of Prakrit incised in a deep-cut Brahmi script on the overhanging brow of a natural cavern called Hathigumpha.
It faces straight towards the Rock Edicts of Ashoka at Dhauli, situated at a distance of about six miles.
