ग्रामीण पायाभूत विकासासाठी _____ या संस्थेने राज्यातील सिंचन प्रकल्प जलदगतीने कार्यान्वित होण्यासाठी विकास निधीची स्थापना केली.

The correct answer is Option A (NABARD).

Key Points:
• The Rural Infrastructure Development Fund (RIDF) was instituted by the Government of India in 1995-96 and placed under the administration of NABARD (National Bank for Agriculture and Rural Development).
• Mandate & Functioning:
• Created to finance State Governments and Panchayati Raj institutions for the expeditious completion of ongoing medium and minor irrigation projects, rural roads, bridges, and flood protection works.
• Commercial banks contribute to the RIDF pool to make up for shortfalls in their mandatory Priority Sector Lending (PSL) agriculture targets.
• While AIBP (Accelerated Irrigation Benefit Programme) is a central budget program, the dedicated fund entity RIDF is maintained and disbursed by NABARD.
• Hence, Option 1 (NABARD) is the correct answer.
• Key Takeaway: RIDF was established in 1995-96 within NABARD to provide low-cost loans to States for completing irrigation and rural infrastructure.
