The correct option is B Permanent Land Revenue Settlement
Permanent settlement of Bengal was introduced in 1793 by Lord Cornwallis. It was introduced in Bengal, Bihar, Orissa, parts of Northern Karnataka, Varanasi and some other areas. The Zamindars needed to pay a fixed amount of land revenue on a fixed date every year. This amount could not be increased later, however, if the Zamindar failed to pay the amount on fixed date, the Company could sell their land via public auction.
