With reference to the passage, the following assumptions have been made : I. Green energy production can be linked to/integrated with the climate change mitigation and adaptation strategies. II. Effects of climate change are much more severe in coastal and mountainous regions. Which of the above assumptions is/are valid ?

The passage discusses green energy production in the context of climate change mitigation and adaptation strategies, so assumption I is directly supported as a valid linkage that the author makes. Assumption II about coastal and mountainous regions being more severely affected by climate change is not mentioned anywhere in the passage; it is an external fact not assumed by the author. In CSAT assumption-based questions, only those assumptions implicit in the passage are considered valid. Hence only assumption I is valid.
