Correct Option (A)
Assumption 1 is valid. The passage explicitly identifies "opportunities for harnessing wind power" in specific regions as a means for "reducing emissions." Green energy production, exemplified by wind power, constitutes a core component of climate change mitigation strategies. Thus, the assumption that green energy production can be linked to climate change mitigation is directly supported by the text.
Incorrect Options:
Assumption 2 is not valid. The passage notes that "coastal States need to take action to protect their shores from sea level rise" and that "Himalayan regions have their own unique challenges." While these statements highlight specific vulnerabilities and adaptation needs in these regions, the passage does not make a comparative claim regarding the severity of climate change effects being "much more severe" in these areas than elsewhere. It describes distinct regional challenges without establishing a hierarchical impact.
Options B, C, and D are incorrect as Assumption 1 is valid, and Assumption 2 is not.
