The correct option is D - 3 only.
[as per provisional answerkey]The question asks to evaluate the logical relationships between three distinct statements regarding environmental protection, scientific consensus, and activism.
Relationship 3 (S2 could be the reason for S3): This is logically plausible. S2 states that there is no scientific consensus on the extent of human contribution to climate change. This lack of definitive consensus or "gray area" provides the vacuum in which "climate alarmism" or "extremist points of view" (mentioned in S3) can flourish. When science is not perceived as settled, both alarmists and deniers use the ambiguity to push their respective agendas. Therefore, S2 can indeed be a contributing factor or "reason" for the phenomenon described in S3.
This question tests the ability to identify logical causality and thematic consistency between statements, specifically distinguishing between a statement's core argument and the external reactions to that argument.
