The correct option is D Ashoka
The earliest deciphered epigraphic inscriptions are the Edicts of Ashoka of the 3rd century BCE, written in forms of Prakrit in the Brahmi script. The inscriptions and edicts of Asoka refer to a collection of 33 inscriptions on the Pillars of Asoka, as well as boulders and cave walls. They are spread over modern-day Afghanistan, Nepal, Bangladesh and Pakistan.
