Which one is correct?

Governors-General and Viceroys of British India are each linked to specific administrative, land-revenue, or social-reform measures. Correctly matching a name to a measure requires matching the person's actual tenure and signature accomplishment, not a superficially similar measure from a different tenure.

Lord Cornwallis served as Governor-General from 1786 to 1793 and introduced the Permanent Settlement (Zamindari System) in 1793 for Bengal, Bihar, and Odisha, fixing the land revenue payable by zamindars in perpetuity in exchange for permanent ownership rights. This pairing of Lord Cornwallis with the Permanent Settlement is factually and historically correct.

• The Doctrine of Lapse was introduced by Lord Dalhousie (Governor-General, 1848-1856), not Lord William Bentinck; Bentinck's tenure (1828-1835) is instead remembered for abolishing Sati Pratha in 1829 and suppressing Thuggee.

• The Abolition of Sati Pratha was carried out by Lord William Bentinck in 1829, not Lord Canning; Canning's tenure (1856-1862) is instead remembered for the Government of India Act, 1858, enacted after the 1857 uprising.

• The Subsidiary Alliance System was introduced by Lord Wellesley (Governor-General, 1798-1805), not Lord Dalhousie; Dalhousie's tenure is instead remembered for the Doctrine of Lapse and for expanding railways and telegraph lines.

Hence, among the given pairs, only Lord Cornwallis - Permanent Settlement correctly matches the Governor-General with his actual policy.
