Final answer:
The Anti-federalists felt that the Constitution shifted the balance of power in favor of the Federal Government (b) and away from the States (b), which they believed would lead to an overpowering national government that could threaten individual freedoms and state sovereignty.
Step-by-step explanation:
Anti-federalists believed that the Constitution tipped the balance of power in favor of b. Federal Government; and away from b. States. They feared a strong national government would overpower state governments, which they believed were closer to the people and better defenders of individual freedoms. These concerns focused on the perceived consolidation of power at the national level with insufficient checks on the executive branch and a lack of a Bill of Rights that might lead to the infringement on individual liberties. The Anti-federalists argued that the Constitution favored the wealthy elite and would result in an aristocratic tyranny, undermining both state sovereignty and the rights of the common people.
