Correct option is D
The correct answer is (d) Iqtadari.
• The Iqtadari System was a land revenue and administrative system used by the Delhi Sultanate, and it later influenced both the Bahmani and Vijayanagar kingdoms in several ways.
• The iqtas were granted to iqta'dars (also called muqtis), who were responsible for collecting taxes, maintaining law and order, and managing their iqtas.
• The Bahmanis adopted the Iqtadari system with modifications, using it to administer their vast territory.
• The Vijayanagar kings also adapted the Iqtadari system, though to a lesser extent.
