Concept:
The Green Revolution refers to the introduction of modern agricultural technology in India during the 1960s and 1970s to increase food grain production.
Major components included:
• High Yielding Variety (HYV) seeds
• Irrigation facilities
• Fertilizers and pesticides
• Mechanization
The Green Revolution produced both economic and social changes in rural India. To answer this question correctly, we must identify the chronological order in which these developments occurred.
Step 1: Introduction of new technology
The first major event of the Green Revolution was the introduction of:
• HYV seeds
• Tractors
• Tube wells
• Chemical fertilizers
Therefore, the process clearly started with:
\[
(B) \text{ New technology introduced}
\]
Step 2: Displacement of service castes
As mechanization increased:
• Tractors replaced animal labour.
• Machines reduced dependence on traditional village artisans.
• Many service castes lost traditional occupations.
Thus, after technology came:
\[
(C) \text{ Displacement of service castes}
\]
Step 3: Spread to dry regions
Initially, the Green Revolution was concentrated in regions with:
• Good irrigation
• Fertile land
Later, technological expansion and irrigation development helped spread agriculture into relatively drier areas.
Hence the next stage was:
\[
(A) \text{ Dry region spread}
\]
Step 4: Increasing commercialization
As production increased:
• Farmers produced more for markets.
• Agriculture became profit-oriented.
• Commercial farming expanded.
This resulted in:
\[
(D) \text{ Increasing commercialization}
\]
Step 5: Writing the correct sequence
Thus, the chronological order becomes:
\[
B \rightarrow C \rightarrow A \rightarrow D
\]
Therefore:
\[
\boxed{\text{B, C, A, D}}
\]
Hence, the correct option is:
\[
\boxed{(1)}
\]
