The correct answer is B. The diagram is completed this way:
1- The United States Constitution is written with no mention of political parties.
2- Alexander Hamilton and James Madison have different views about the power of the federal government.
3- The two-party system emerges with the creation of the Federalist and Democratic-Republican parties.
The diagram shows how American political parties emerged in response to the need of politicians of the time to create platforms to defend their convictions and ideals.
Thus, the Federalist Party emerged to defend the ideals of Alexander Hamilton, while the Democratic-Republican Party did so to strengthen the policies of James Madison.
