S1: The definition of large farmers differs from state to state in India.
S6: This trend increased the income base of those who were already relatively well-off and better placed in society.
P: In the initial phase of the Green Revolution, the large farmers were able to adopt the High Yielding Varieties easily.
Q: The new varieties increased their savings, both to buy machinery that can displace labour and to purchase more land.
R: For example, a farmer having 10 acres in Kerala is a large farmer, while in Rajasthan, Punjab and Haryana he falls under the category of a small or medium farmer.
S: All the studies conducted in areas where Green Revolution is a success show that the large farmers have been the main gainers of the package programme.

The correct answer is 'Option 2'.

Key Points

• S1: The definition of large farmers differs from state to state in India.
  • This sentence introduces the varying definition of "large farmers."
• R: For example, a farmer having 10 acres in Kerala is a large farmer, while in Rajasthan, Punjab and Haryana he falls under the category of a small or medium farmer.
  • This sentence provides a direct example that illustrates the statement made in S1, making it the most logical immediate follow-up.
• S: All the studies conducted in areas where Green Revolution is a success show that the large farmers have been the main gainers of the package programme.
  • After establishing the varying definition of large farmers (S1, R), this sentence introduces the significant role of these large farmers as "main gainers" in the context of the Green Revolution.
• P: In the initial phase of the Green Revolution, the large farmers were able to adopt the High Yielding Varieties easily.
  • This sentence logically follows S by explaining why large farmers were the main gainers – their ability to easily adopt High Yielding Varieties (HYVs) due to their resources.
• Q: The new varieties increased their savings, both to buy machinery that can displace labour and to purchase more land.
  • This sentence details the positive consequences for large farmers from adopting the "new varieties" (HYVs) mentioned in P, linking their increased savings to further investments.
• S6: This trend increased the income base of those who were already relatively well-off and better placed in society.
  • This concluding sentence summarizes the outcome of the process described in Q, directly referring to the accumulated wealth and land acquisition as the "trend" that further enriched the already well-off.
• The sequence R-S-P-Q creates a coherent narrative: defining large farmers (S1, R), showing their overall gains in Green Revolution (S), explaining how they gained (P), and detailing the consequences of those gains (Q), which then leads to the final summarizing statement (S6).
