The correct option is A Bhabhru Edict
In Bhabhru edict, the Mauryan Emperor Ashoka refers himself as Piyadassi laja Magadhe (Piyadassi, King of Magadha). In this edict he states his faith in the Buddha, the Dhamma and the Sangha. Hence, Option A is correct. In the Queen's Edict, Ashoka announces that the Queen Karuvaki should be credited for her gifts. The Dhauli Pillar Inscriptions are based on Kalinga War. The Maski version of Minor Rock Edict No.1 is historically particularly important in that it confirmed the association of the title "Devanampriya" with the name "Asoka", thereby clarifying the historical author of all these inscriptions.Hence, these options are incorrect.
