Explanation:

Anti - Federalists were against the ratification of the US Constitution. They feared a strong central government (the Constitution aimed at a stronger federal government) and wanted more power for individual states. The establishment of slavery was not a main Anti - Federalist opposition point, they were not against a bill of rights (in fact, they pushed for it), and they supported strong individual state governments (so not opposed to that).

Answer:

A. ratification of the US Constitution.
