In the context of which of the following do you sometimes find the terms 'amber box, blue box and green box' in the news?

The terms 'amber, blue, and green boxes' refer to the classification of domestic subsidies under the World Trade Organization’s (WTO) Agreement on Agriculture based on their level of trade distortion. While the term 'green box' might tempt candidates to choose UNFCCC (Option C) due to its environmental connotation, these boxes specifically categorize agricultural support measures rather than climate change policies. The core concept tested is the multilateral framework governing international trade and the regulation of domestic agricultural subsidies.
