Option d is the correct answer. The edict that mentions the personal name of Ashoka is the one found at Maski. The Maski edict is part of Ashoka's Minor Rock Edicts, issued in the 3rd century BCE. It's in Maski, Karnataka, inscribed in Brahmi, and dated to Ashoka's 25th year. This edict is significant because it contains the name "Ashoka," whereas earlier edicts referred to him as "Devanampiye Piyadasi." The discovery of this edict at Maski provided important historical insights into the life and reign of Emperor Ashoka.
