Explanation:

China — the world’s biggest polluter — pledged to inject $233 million into the Kunming biodiversity fund to protect biodiversity in developing countries during a key UN conservation summit.

• The summit aims to establish a new accord setting out targets for 2030 and 2050.
• A key proposal being debated at the conference is the “30 by 30” agenda that would afford 30% of the Earth’s land and oceans protected status by 2030.
• Global spending to protect and restore nature needs to triple this decade to about $350 billion annually by 2030 and $536 billion by 2050 to meet this target, a UN report said in May 2021.
• But some rich country donors say a new fund for conservation is unnecessary because the United Nations’ Global Environment Facility already helps developing nations finance green projects.
• Kunming, also known as Yunnan-Fu, is the capital and largest city of Yunnan province, China.
• It is at the northern edge of Dian Lake.

Hence option 2nd is correct.
