What is the first phrase of the U.S. Constitution?

The first phrase of the U.S. Constitution is "We the people of the United States, in order to form a more perfect union." This opening statement is significant as it establishes the foundational principle of the document, which is that the government derives its power from the consent of the governed. It emphasizes the collective identity of the citizens and highlights the purpose of the Constitution: to create a more unified and effective government that can serve the interests of all its people. This phrase reflects the democratic ideals upon which the United States was founded, focusing on unity, cooperation, and the role of the populace in shaping their government.

The other choices, while they might reflect important ideas related to governance or historical documents, do not represent the initial words of the U.S. Constitution itself, which is crucial for understanding the document and its intent.
