The world’s largest dairy development program designed and implemented in India is called as
A. White Revolution
B. Golden Revolution
C. Operation flood
D. Silver Revolution

Hint: The White Revolution is the period in which India became self-sufficient regarding dairy production. From 1970 to 1998 India launched a dairy development program that made India the largest producer of milk in 1998.

Complete answer:
Verghese Kurien the milkman of India, was a mechanical engineer and a social entrepreneur whose idea of ‘Operation Flood’ gave rise to dairy farming in India. Operation Flood was launched in 1970 under Dr. Kurien. This program linked all the milk producers across India to the consumers in over more than 600 towns and cities reducing the seasonal and regional price of milk. He also ensured that the milk producers across India get the major share of profit by eliminating the middleman.
The main objectives of Operation Flood's largest dairy program were: Increasing milk production in India, raising the income in rural areas, providing fair prices for the consumers, and reducing poverty in farmers, and increasing their income.
It also led to an increase in demand for the development and production of healthy animals, networking between many small scale and large scale dairy industries, and increased use of modern technology in milk production.

Hence, the correct option is option (C), Operation Flood.

Note:
Out of total milk produced in developing countries, up to 80 to 90 percent of milk is produced in small-scale farming systems. India ranks first in the production of milk contributing up to 22 percent of global production. It is important to remember that the program Operation Flood leads to the White Revolution in India.
