Explanation:

• The NCQG (New Collective Quantified Goal) was established in the 2015 Paris Climate Agreement to set a reference point for climate financing by 2025, considering the needs and priorities of developing nations.Hence, statement 1 is correct.

• Climate finance refers to the provision of financial support at local, national, or transnational levels to address climate change through mitigation and adaptation actions. It can involve funding for mitigation, adaptation, capacity building, and technology transfer in developing countries. Hence, statement 2 is correct.

• In international climate negotiations, the principle of common but differentiated responsibilities (CBDR) is often invoked, which recognizes that developed countries, historically responsible for most greenhouse gas emissions, should take the lead in addressing climate change. The burden of achieving net-zero emissions and transitioning to sustainable pathways is seen as a shared responsibility, but with developed countries taking greater responsibility due to their historical emissions and greater capacity. Hence, statement 3 is incorrect.

Therefore, option 1st is correct.
