The unique feature of whose administrative system was the development of village autonomy?

The correct answer is (B) Chola.

• The Chola administrative system is globally renowned for its highly organized local self-government, specifically the village autonomy documented in the famous Uttaramerur inscriptions (Parantaka I).
• The village administration functioned through assemblies known as Sabhas (Brahmin settlements) and Urs (general villages), which managed tax collection, land surveys, and local justice, demonstrating a highly decentralized and efficient governance model.
• The Cheras were known for their maritime trade, Pandyas for their cultural patronage and early urban centers, and Pallavas for their unique Dravidian temple architecture and administrative centralism, distinct from the village-focused decentralization of the Cholas.
