In the United States, law is predominantly derived from which of the following?

In the United States, the law is predominantly derived from legislative bodies, which includes Congress at the federal level and state legislatures at the state level. Legislative bodies create statutes and regulations that govern various aspects of society, covering everything from civil rights to public health. These laws reflect the will of the people as expressed through their elected representatives.

While other sources like voter referendums, executive orders, and international courts play a role in shaping law, they do not constitute the primary source. Voter referendums allow citizens to vote directly on specific legislative issues, but their occurrence is limited and subject to legislative approval. Executive orders are directives issued by the President or governors that manage operations of the federal or state government, but these cannot create laws in the same way that legislation can. International courts influence international law and treaties but do not typically create domestic law in the United States. Therefore, legislative bodies are the cornerstone of lawmaking in the U.S., making this the correct answer.
