Final answer:
The Anti-Federalists argued that the Constitution lacked a bill of rights to protect individual liberties; the Federalists promised to add one as a compromise for ratification, making option (C) Both A and B the correct answer.
Step-by-step explanation:
The Anti-Federalists' strongest argument against the Constitution was that it lacked a bill of rights to protect individual liberties. This concern is captured in options A and B. The Anti-Federalists demanded that the Constitution clearly guarantee people's freedoms (A), and as a compromise, the Federalists promised to add a bill of rights (B). Therefore, the correct answer to the provided question is (C) Both A and B.
The Anti-Federalists argued that a strong federal government could lead to an expansion of powers and potentially threaten individual rights and freedoms. The lack of a bill of rights in the original Constitution was particularly concerning for many of them. To address these concerns and ensure the ratification of the Constitution, the Federalists compromised by promising to add a bill of rights that would protect key freedoms like speech, press, and assembly, which were later included as the first ten amendments to the Constitution.
