3. S1 : From an importer of milk powder to the world's largest milk producer.
S6 : And to think that it began as a simple experiment in a village in Gujarat only in the 1960s.
P : Operation Flood is arguably India's biggest and most successful revolution since the Quit India Movement.
Q : India's Operation Flood has come a long way from the days when even baby food was imported to producing 84 million tonnes a year.
R : From abject desperation to becoming a global player in the dairy sector.
S : From a mere few villagers and a 275-litre processing plant to an operation spread across 23 States, 170 Districts and 90,000 Village Cooperatives.
The correct sequence should be :
- AP - S - Q - R
- BR - Q - S - P
- CP - Q - S - R
- DR - S - Q - P
Explanation
S1 frames the transformation arc (milk-powder importer to world's largest milk producer), and P names it: Operation Flood. Q quantifies the journey — from importing even baby food to producing 84 million tonnes a year. S then shows the organizational scale (23 States, 170 Districts, 90,000 Village Cooperatives), and R ("from abject desperation to becoming a global player") bridges to S6's punchline: it all began as a simple experiment in a Gujarat village in the 1960s. Hence P-Q-S-R.
