Explanation:

- Lord Lytton: He was the Viceroy of India from 1876 to 1880. Lord Lytton organized the Delhi Durbar in 1877 to proclaim Queen Victoria as the Empress of India. This grand event was intended to showcase the power of the British Empire.

- Lord Ripon: He served as the Viceroy of India from 1880 to 1884. Known for his liberal policies, Lord Ripon focused on social reforms and local self-government, rather than grand displays like the durbar.

- Lord Minto: His term as Viceroy was from 1905 to 1910. He is remembered for political reforms known as the Minto-Morley Reforms, not related to any durbar.

- Lord Dufferin: Serving from 1884 to 1888, Lord Dufferin was involved in expanding the British Empire, but not the organizer of the 1877 durbar.
