कृषी क्षेत्राच्या पुनरुज्जीवनासाठी राष्ट्रीय शेतकरी आयोगाने खालील उपाय सुचविले : (a) सर्व शेतकऱ्यांची कर्ज माफी (b) मृदा आरोग्य सुधारणा (c) पाण्याचा कार्यक्षम वापर (d) पत सुधारणा पर्यायी उत्तरे :

The correct answer is Option C ((b), (c) and (d)).

Key Points:
• The National Commission on Farmers (NCF), chaired by Dr. M.S. Swaminathan, made comprehensive recommendations for the holistic revival of Indian agriculture.
• Soil health enhancement (b): Stressed soil testing, micro-nutrients, and soil health cards.
• Efficient use of water (c): Recommended ' Pani Panchayat' models, rainwater harvesting, and micro-irrigation (drip/sprinkler).
• Credit reforms (d): Suggested institutional credit restructuring, lowering interest rates, and rescuing farmers from indebtedness.
• Debt waiver for all farmers (a): While NCF recommended relief measures, comprehensive blanket debt waiver for *all* farmers across the board was not its primary systemic prescription (rather it focused on institutional credit access and safety nets).
• Therefore, (b), (c), and (d) are the core suggested plans, making option (3) correct.
• Key Takeaway: The Swaminathan Commission recommended soil health enhancement, efficient water use, and credit reforms for agricultural revival.
