아래 지문에서 관련 없는 문장이 C라는데, 저는 한글해석을 읽어도 왜 답이 C가 되는지 모르겠습니다.

지문 주제가 확실히 무엇인지 몰라서 왜 C가 상관이 없는지 모르는 것 같아요.

Economic liberalism is the principle driving capitalist economies and the rationale behind the US business sector’s dearth of government regulation. (a) This principle assumes that self-interest motivates people to create the optimal conditions for successful economic activity. (b) Therefore, letting businesses act unfettered by restrictions should result in universal economic prosperity. (c) To this end, history has proven how a permissive regulatory environment has led to reckless and abusive business practices. (d) Supposedly, businesses will refrain from acts that exploit consumers because they know this will adversely affect the company’s bottom line.
