Which document is described as the supreme law of the land?

• A. The U.S. Constitution
• B. The Declaration of Independence
• C. The Northwest Ordinances
• D. The Articles of Confederation

Answer: (A)

The main concept being tested is identifying the document that serves as the supreme law of the land—the highest authority guiding both federal and state laws. The United States Constitution earns that status because the Supremacy Clause states that the Constitution, federal laws, and treaties are the supreme law of the land, binding over state constitutions and statutes. This creates a single, overarching framework for government and ensures that federal and state actions must conform to the Constitution. The other documents have important historical roles but do not establish this overarching legal authority: the Declaration of Independence explains why independence was sought and outlines broad principles, the Articles of Confederation created a weak central government, and the Northwest Ordinances governed territorial matters under that earlier framework.
