Answer:

The correct answer is C. At the end of the Constitutional Convention, the Constitution was signed by 39 delegates.

Explanation:

The Constitution is the supreme law of the United States. It was drafted in its original form by the members of the Constitutional Convention of Philadelphia and endorsed with its signature by 39 of the 55 participant delegates on September 17, 1787, almost two years before the French Revolution, which makes it the oldest constitutional text still in force in the world. The Philadelphia Convention is one of the central episodes in the history of the United States, and prominent figures such as James Madison, Alexander Hamilton, Benjamin Franklin, and George Washington participated in it.
