In Chola revenue administration, the term Nadu was associated with which unit?

Group of villages

The governing concept is the layered local administration of the Chola kingdom. A village was an important basic unit, and several villages were grouped into a larger territorial unit called a Nadu. This arrangement helped organise revenue collection, irrigation, local responsibilities and communication between villages and higher authorities. Therefore option A is correct: Nadu meant a group or cluster of villages, not an object or literary work. A Harappan seal belongs to the much earlier Indus civilisation, a Buddhist text is a religious-literary category, and a Mauryan pillar is an imperial monument associated with another dynasty and period. These distractors are historically real terms, but none describes the Chola administrative unit Nadu.
