Explanation
1. The question asks which of Asoka's major rock edicts mention the Sangam Kingdom(s).
2. The Sangam Kingdoms refer to the Cholas, Pandyas, Cheras (Keralaputras), and Satiyaputras located in South India, beyond Ashoka's direct rule.
3. Rock Edict II of Ashoka mentions medical missions sent for men and animals not only within his empire but also to neighbouring territories, explicitly naming the Cholas, Pandyas, Satiyaputra, Keralaputra, and Tamraparni (Sri Lanka), as well as Greek kingdoms.
4. Rock Edict XIII, primarily describing the Kalinga War and Ashoka's Dhamma Vijaya (conquest by Dhamma), also lists several neighbouring kingdoms, including the Cholas, Pandyas, Keralaputras, and Satiyaputras, where Ashoka spread his message of Dhamma.
5. Therefore, Rock Edicts II and XIII provide information about the Sangam Kingdoms during Ashoka's time.
6. Option (C) correctly identifies these two edicts.
