Answer:
A. They often lack the resources to solve the challenges of climate change.
Step-by-step explanation:
Nations in Southeast Asia, such as Indonesia, the Philippines, and Vietnam, are predicted to be some of the most affected by climate change in the future due to their vulnerability to its impacts. These countries are highly dependent on agriculture and fisheries, which are highly sensitive to changes in climate, and have large coastal populations that are at risk of flooding and sea-level rise. In addition, many of these countries have limited resources to adapt to the challenges of climate change, such as implementing new infrastructure or relocating populations from vulnerable areas. This lack of resources makes it difficult for them to address the challenges of climate change, making them more vulnerable to its impacts.
