During 1967 food crisis, Zoning policy of the government refers to:

Prohibition of trade of food across the states

The correct answer is option (3) - Prohibition of trade of food across the states

Bihar was prone to food crises in the early years of independence. There was a near-famine situation. The food shortage was very much acute in all districts of Bihar. Food shortage led to acute and widespread malnutrition. The zoning policies of the government prohibited the trade of food across states, which reduced the availability of food in Bihar.
