Which scripts were used across Ashoka's inscriptions?

The correct answer is Brahmi, Kharosthi, Greek and Aramaic. Most Ashokan inscriptions use Brahmi; the northwest uses Kharosthi, and inscriptions in the Afghan region also employ Greek and Aramaic. Devanagari developed much later. A strong answer should connect the term or object with its precise source, location, ruler, regnal context, and administrative function.
