Option C: Territorial unit between Subah and Paragnah, but not identical to Sarkar
Detailed Solution:
The correct answer is “Territorial unit between Subah and Paragnah, but not identical to Sarkar”.
The term 'chakla' was used in the medieval period for a territorial unit that was larger than a Paragana but smaller than a Sarkar.
It was a revenue collection unit and was headed by a Chakladar.
The term was used particularly in the Delhi Sultanate and the Mughal Empire. The Chakla system was replaced by the Pargana system during the later Mughal period.
