What institution determines and enforces a society's laws?

• A. State
• B. Citizen
• C. County
• D. Government

Answer: (D)

The main idea here is who has the authority to create and enforce the rules that govern everyone in a society. The government is the organized system that does both: it makes laws through its legislative processes, enforces them through police and executive agencies, and resolves disputes in courts. While a state can refer to the political entity or government of a country, and a county is just a local administrative unit, and a citizen is an individual who must follow laws, only the government as a whole encompasses the power to determine and enforce those laws across society. That makes it the best answer.
