The correct option is
C Verghese Kurien
Verghese Kurien known as the 'Father of the White Revolution' in India,[2] was a social entrepreneur whose "billion-litre idea", Operation Flood, the world's largest agricultural dairy development programme, made dairy farming India's largest self-sustaining industry and the largest rural employment provider, being a third of all rural income, with benefits of raising incomes and credit, riddance of debt dependence, nutrition, education, health, gender parity and empowerment, breakdown of caste barriers and grassroots democracy and leadership. It made India the world's largest milk producer from a milk-deficient nation, which doubled milk available per person and increased milk output four-fold, in 30 years. A key invention at Amul, the world's first, was the production of milk powder from the abundant buffalo-milk, instead of from the conventional cow-milk, short in supply in India. Keen on a strong linkage between town and country, he surmounted skepticism and adversity with his indefatigable fighting spirit and outmaneuvering skills to capture a commanding share of the market of the city of Bombay (now, Mumbai), which got him wide attention.
So the correct option is 'Verghese Kurien'.
