The correct answer is A. Federalists wanted a strong central government, but Democratic-Republicans wanted strong states.
The Federalists, led by figures like Alexander Hamilton, advocated for a strong central government and believed in a loose interpretation of the Constitution, which allowed for more federal power. On the other hand, the Democratic-Republicans, led by Thomas Jefferson and James Madison, favored states' rights and a strict interpretation of the Constitution, emphasizing the power of individual states over the federal government.
