The Asokan major rock edicts which tell us about the Sangam Kingdom include rock edicts

Major Rock Edict II explicitly records southern polities — naming the Pandyas, Satyaputras (Satiyaputa) and Keralaputras — thereby identifying kingdoms of the Tamil/Sangam world in Ashoka’s inscriptions. Major Rock Edict XIII similarly lists southern polities, mentioning the Cholas and Pandyas while describing the reach or influence of Ashoka’s dhamma, which again ties the edicts to Sangam-era rulers and regions. Contemporary summaries of the edicts compile these references (Cholas, Pandyas, Satiyaputras, Keralaputras, Tamraparni) as evidence linking Ashokan inscriptions to the Sangam kingdoms, reinforcing that Edicts II and XIII are the relevant sources [1]. Hence the correct choice is II and XIII (option 3).
