Tenant can be ejected if transferee obtains possession after void transfer:

The correct answer is Collector order. In many land revenue and administration systems, the Collector (or Deputy Commissioner) is vested with significant powers to manage government lands and resolve disputes, including ordering the ejectment of tenants. If a transfer is void, the subsequent possession by a transferee is unlawful, and the Collector, as the primary revenue authority, can issue an order for ejectment to rectify the situation efficiently. 'Civil court only' is incorrect because revenue authorities often have concurrent or primary jurisdiction in such matters. 'After 7 years' and 'Never' are arbitrary and incorrect timeframes or conditions for ejectment in cases of void transfers.
