Step 1: Understanding the Concept:
Agricultural "revolutions" in India refer to specific, targeted national campaigns and technological advancements introduced to rapidly increase the production of key food commodities.
Step 2: Detailed Explanation:
Let us match each agricultural revolution with its corresponding commodity:
(A) Green Revolution:
Launched in the mid-1960s with the introduction of high-yielding, semi-dwarf wheat and rice varieties (such as those developed by Norman Borlaug and introduced to India by M. S. Swaminathan), this initiative led to a massive increase in food grain production, especially wheat.
Hence, (A) matches with (III).
(B) White Revolution:
Known as "Operation Flood," this dairy development program was launched in 1970 by the National Dairy Development Board (NDDB) under the leadership of Verghese Kurien.
It transformed India from a milk-deficient nation into one of the world's largest milk producers through a national cooperative network.
Hence, (B) matches with (I).
(C) Blue Revolution:
This initiative focused on the rapid growth, modernization, and development of the fisheries and aquaculture sector in India to increase fish production and support coastal communities.
Hence, (C) matches with (II).
(D) Yellow Revolution:
Launched in 1986-87, this campaign targeted self-sufficiency in oilseed production (such as mustard, groundnut, and soybean) through technological intervention and support to farmers.
Hence, (D) matches with (IV).
Step 3: Final Answer:
The correct matching sequence is:
(A) - (III), (B) - (I), (C) - (II), (D) - (IV).
This corresponds to Option (B).
