The correct answer is Option D (Dadabhai Naoroji and M.G. Ranade).

Key Points:
• Economic nationalism (Drain of Wealth theory and critique of British colonial economic policies) was systematically formulated and articulated in India by Dadabhai Naoroji and Justice Mahadev Govind Ranade.
• Dadabhai Naoroji exposed the economic exploitation through his 'Drain Theory' and book 'Poverty and Un-British Rule in India'.
• M.G. Ranade provided the theoretical foundation for Indian economic nationalism, emphasizing protectionist industrial policies and critiquing free-trade imperialism.
• Thus, Dadabhai Naoroji and M.G. Ranade are recognized as the pioneers who put forward economic nationalism, matching Option (2)/(4) in the official question paper (Option 4 text duplicates Option 2 in Marathi/English alignment context, but the correct historical figures are Dadabhai Naoroji and M.G. Ranade).
• Key Takeaway: Dadabhai Naoroji and M.G. Ranade pioneered the theory of economic nationalism and the critique of British economic drain.
