The crop insurance schemes in India evolved over time to address the needs of farmers. The correct chronological order is:
1. Pilot Crop Insurance Scheme (1979): Introduced as an experimental initiative to provide insurance coverage to farmers against crop losses in select areas.
2. Comprehensive Crop Insurance Scheme (1985): Expanded the scope of the Pilot scheme, offering broader coverage but limited to specific crops and farmers with crop loans.
3. National Agricultural Insurance Scheme (NAIS, 1999–2000): A more extensive scheme aimed at covering all farmers and a wider range of crops, with improved risk coverage.
4. Pradhan Mantri Fasal Bima Yojana (PMFBY, 2016): A flagship scheme with comprehensive risk coverage, lower premiums, and technology-driven implementation (e.g., remote sensing for loss assessment).
Thus, the sequence (A), (B), (C), (D) corresponds to the chronological order, making option (1) correct.
