Consider the following statements : Statement I : Article 6 of the Paris Agreement on climate change is frequently discussed in global discussions on sustainable development and climate change. Statement II : Article 6 of the Paris Agreement on climate change sets out the principles of carbon markets. Statement III : Article 6 of the Paris Agreement on climate change intends to promote inter-country non-market strategies to reach their climate targets. Which one of the following is correct in respect of the above statements?

Option (a) is correct because Article 6 establishes the framework for international cooperation through both market-based mechanisms (carbon markets under 6.2 and 6.4) and non-market approaches (under 6.8), which are the core concepts tested here. Since these two pillars provide the primary pathways for countries to achieve their Nationally Determined Contributions (NDCs) collaboratively, they collectively explain why Article 6 is a central topic in global climate discussions (Statement I). Option (b) is the most tempting wrong choice, but it is incorrect because it fails to recognize that non-market strategies are just as fundamental to the Article 6 framework as carbon markets, and both are equally responsible for its prominence in international policy.
