Which writing supported the ratification of the U.S. Constitution?

The Federalist Papers were a series of articles and essays written by Alexander Hamilton, James Madison, and John Jay to support the ratification of the U.S. Constitution. They were published in newspapers and aimed to persuade the public and the state legislators of the necessity and advantages of adopting the new Constitution. The writings addressed concerns about the structure of the new government, the separation of powers, and the protection of individual liberties, ultimately helping to lay the foundation for a strong federal government that could operate effectively while still safeguarding the rights of citizens.

The other options are significant documents in their own right but do not serve the same purpose as the Federalist Papers in the context of ratifying the Constitution. The Magna Carta introduced the idea of limited government and individual rights centuries earlier, but it did not pertain to the U.S. Constitution. The Emancipation Proclamation, issued during the Civil War by President Abraham Lincoln, aimed to free enslaved individuals in Confederate states, while the Bill of Rights is a collection of amendments added to the Constitution to protect individual freedoms but came after the Constitution was ratified. Therefore, the Federalist Papers directly supported the ratification process, making it the correct response.
