जागतिक व्यापार संघटनेच्या (WTO) तरतुदींनुसार, उत्पादन कमी करण्यासाठी शेतकऱ्यांना दिली जाणारी प्रोत्साहनात्मक प्रदाने या गटात दाखविली जातात :
(1) हिरवी पेटी
(2) पिवळसर लाल पेटी
(3) निळी पेटी
(4) निळी व पिवळसर लाल पेटी

The correct answer is Option C (blue box).

Key Points:
• Core Concept
• The WTO Agreement on Agriculture (AoA) categorizes domestic agricultural support into three traffic-light colored 'boxes': Green, Amber, and Blue.
• Why Correct
• Blue Box subsidies refer to Amber Box supports with production-limiting conditions. Direct payments made under production-limiting programs (such as payments tied to fixed areas and yields or number of livestock to restrict output) are placed in the Blue Box.
• These are exempt from reduction commitments under Article 6.5 of the WTO AoA.
• Key Details
• Green Box: Non-trade-distorting subsidies (research, pest control, food security stocks).
• Amber Box: Trade-distorting price supports subject to limits.
• Exam Traps
• Production limitation is the defining statutory distinction of the Blue Box versus the Amber Box.
• Other Options
• Green Box covers decoupled supports that cause minimal distortion.
• Amber Box includes direct market price supports (like MSP) that distort production.
• Key Takeaway: WTO Blue Box subsidies encompass direct payments designed to limit agricultural production under fixed quotas.
