The correct answer is B) They became a galvanizer for support for the Constitution.
The role that “The Federalist Papers” contributed to the conversation of the American public at this time was that they became a galvanizer for support for the Constitution.
The Federalist Papers were a series of articles -85 to be specific- written by prominent politicians of the time such as James Madison, Alexander Hamilton, and John Jay that used the pseudonym of "Publius." The Federalist Papers intended to support the ratification of the Constitution in times when the anti-federalists such as Thomas Jefferson did not support the idea of a strong federal government.
