The correct answer is A) political factions.
. . . different opinions concerning religion, concerning government, and many other points . . . have, in turn, divided mankind into parties . . . and rendered them much more disposed to [anger] and oppress each other than to co-operate for their common good. —James Madison, Federalist Paper 10
James Madison is describing political factions.
Negotiations to approve the United Constitutions were not easy. There was so much debate and arguments between the delegates that assisted the Convention. The federalists -led by Alexander Hamilton- decidedly supported the creation of a strong central government. That was not the case for Thomas Jefferson's antifederalists. They considered that a strong federal government could turn into tyranny if it had no limits. That is why James Madison, Jhon Jay, and Alexander Hamilton wrote The Federalists Papers, a series of 85 documents under the synonym of "Publius," to promote the ratit¿fication of the US Constitution.
