The correct option is B project flood
To increase the production of milk in India, a program was launched in the 1970s known as the 'White Revolution', which is also termed as 'Operation Flood'. Operation Flood was launched as a project of the National Dairy Development Board (NDDB), which was the world's biggest dairy development program, that put India, from a milk-deficient nation to ultimately world's largest milk producer, surpassing the USA in 1998. It made dairy farming India’s largest self sustainable rural employment generator. Since milk is the only commodity which has to be collected twice a day, every day of the year. Thus, cooperatives are the only logical system for the dairy industry.
Dr. Verghese Kurien is considered as the father of White revolution.
