- Sakyas were the clan of Siddhartha Gautama, with their capital at Kapilavastu. This is correctly matched. - Koliyas were a neighbouring clan of the Sakyas, residing near the Rohini river. Ramagrama was a Koliya stronghold. This is correctly matched. - Mallas were a republican confederacy divided into two main branches, one with its capital at Pava and the other at Kusinara (Kusinagara), where the Buddha attained Mahaparinirvana. This is correctly matched. - The Kalamas were a tribal group associated with the town of Kesaputta, where the Buddha delivered the famous Kalama Sutra. Alara Kalama was a teacher whom Siddhartha Gautama visited. Allakappa was the capital of the Bulis, another republican tribe who received a share of the Buddha's relics. Therefore, Kalamas are associated with Kesaputta, not Allakappa.
