What is stated in the Preamble of the U.S. Constitution?

The Preamble of the U.S. Constitution serves as an introductory statement that articulates the foundational goals and purposes of the document. It establishes the principles upon which the Constitution is built, such as promoting justice, ensuring domestic tranquility, providing for the common defense, promoting the general welfare, and securing the blessings of liberty for both current and future generations. This encapsulation of intentions is crucial for understanding the framers' vision for the nation and what they aimed to achieve through the Constitution.

The other choices focus on different aspects of the Constitution. While the structure of the government is detailed in the main body of the Constitution, and individual rights are listed in the Bill of Rights and other amendments, the Preamble specifically addresses the overarching objectives rather than the structural or rights-based details. The amendment process is also outlined in a separate section of the Constitution and is not part of the Preamble's content. This context helps clarify why the focus on goals in the Preamble distinctly marks the correct answer.
