What arguments did the federalists use against the bill of rights?

Federalists argued that the Constitution did not need a bill of rights, because the people and the states kept any powers not given to the federal government. Anti-Federalists held that a bill of rights was necessary to safeguard individual liberty. That is, the Anti- Federalists claimed the Constitution gave the central government too much power, and without a Bill of Rights the people would be at risk of oppression.

the answer is option a.
