A) the Magna Carta INCORRECT The Magna Carta, signed in 1215, was a landmark document in English history that limited the king's power and established certain legal rights. It influenced the development of constitutional law, including concepts like due process and trial by jury, but it is not the supreme law of the United States. It applies to English law and has no direct legal authority in the U.S. legal system.
B) the U.S. Constitution CORRECT The U.S. Constitution is the supreme law of the land, as explicitly stated in Article VI, Clause 2, known as the Supremacy Clause. This means that all federal laws, treaties, and state constitutions must conform to the Constitution, and judges are bound by it. It establishes the framework of the federal government and protects the fundamental rights of citizens.
C) the Mayflower Compact INCORRECT The Mayflower Compact was an agreement signed in 1620 by the Pilgrims aboard the Mayflower. It established a rudimentary form of self-government for the Plymouth Colony, based on the consent of the governed. While historically significant as an early example of democratic governance in America, it was not a national constitution and has no legal standing today.
D) the Declaration of Independence INCORRECT The Declaration of Independence, adopted on July 4, 1776, announced the colonies' separation from Great Britain and articulated the principles of individual liberty and government by consent. It is a foundational document of American ideals but does not establish a government or laws. It is not the supreme law of the land; that role belongs to the Constitution.
