Answer:
A. A Constitution that did not contain a Bill of Rights
Step-by-step explanation:
The Anti-Federalists were concerned about the lack of explicit protections for individual liberties in the proposed Constitution. They argued that without a Bill of Rights, the central government could potentially infringe upon the rights and freedoms of the people. Adding a Bill of Rights became a significant point of contention during the ratification debates, and it was eventually included in the Constitution as the first ten amendments, addressing these concerns raised by the Anti-Federalists.
