How was ratification of the new constitution made easier?

The ratification process started when the Congress turned the Constitution over to the state legislatures for consideration through specially elected state conventions of the people. Five state conventions voted to approve the Constitution almost immediately (December 1787 to January 1788) and in all of them the vote was unanimous (Delaware, New Jersey, Georgia) or lopsided (Pennsylvania, Connecticut). Clearly, the well-organized Federalists began the contest in strong shape as they rapidly secured five of the nine states needed to make the Constitution law. The Constitution seemed to have easy, broad, and popular support.

The answer is c. good luck : )
