Answer:
85 essays and articles written to convince people to pass the new Constitution.
Step-by-step explanation:
The "Federalist Papers" is a series of essays, a collection of 85 essays that Alexander Hamilton, John Jay, and James Madison wrote together. These papers were written under their collective pseudonym "Publius", and contained arguments that supported the passing of a new Constitution of the United States.
These essays argued for a stronger central government and promoted the institution of a strong Constitution. Hamilton collaborated with Jay and Madison to write about the need for such a government and how it will be the making for a strong and united America.
Thus, the correct answer is the third option.
