The correct response indicating the circumstances preceding the ratification of the Constitution is:
Many supporters of the Constitution claimed that a national bill of rights was not necessary.
This reflects the argument made by several Federalists during the ratification debates. They believed that the Constitution itself was a bill of rights in the sense that it limited the powers of the federal government. However, the absence of a specific bill of rights was a significant concern among Anti-Federalists, ultimately leading to the adoption of the Bill of Rights as the first ten amendments to the Constitution in 1791.
