Correct answer: (b) Bengal, Bihar and Orissa

Explanation

Lord Cornwallis introduced the Permanent Settlement in 1793 in Bengal, Bihar and Orissa (and later in Banaras and parts of Madras). The zamindars became owners of the land and paid a revenue fixed for ever.

The zamindars kept about one-eleventh of the rent they collected and paid ten-elevenths to the Company. If they failed to pay by sunset on the fixed date, their estates were sold; this was called the sunset law.
