Concept:
Honorific titles in Indian nationalism were given to leaders who made long-standing intellectual, political, and organizational contributions to the freedom movement. One such leader was Dadabhai Naoroji, whose work spanned both economic critique and political leadership.
Step 1: Identifying Dadabhai Naoroji
• Dadabhai Naoroji (1825–1917) was one of the earliest Indian political leaders and co-founder of the Indian National Congress (1885).
• He served as President of INC three times.
• He was the first Indian member of the British Parliament.
Step 2: Why he is called “Grand Old Man of India”
He earned this title due to:
• His long and continuous political service to India.
• His pioneering economic critique of British colonial rule.
• His famous “Drain of Wealth” theory explaining economic exploitation.
Step 3: Eliminating incorrect options
• Gokhale: Known as political mentor of Gandhi, not this title.
• A. O. Hume: Founder of INC but British administrator.
• M. G. Ranade: Social reformer and judge, not associated with this title.
Thus, Dadabhai Naoroji is the correct answer.
