Final answer:
The Federalists supported a strong central government, while the Anti-Federalists feared such centralization would infringe on individual rights and demanded a Bill of Rights. The correct answer is option a) and d).
Step-by-step explanation:
The disagreements between Federalists and Anti-Federalists were rooted in their conflicting visions of the structure and power of the government in the newly-formed United States of America. a) The Federalists indeed supported a strong central government, believing that a centralized republic provided the best solution for the future. On the other hand, d) the Anti-Federalists feared that a centralized government would infringe on individual rights and argued vigorously for the inclusion of a Bill of Rights to protect such freedoms.
Options b) and c) are incorrect because Anti-Federalists were the proponents of the Bill of Rights, and it was the Federalists who wanted to move away from the Articles of Confederation in favor of the new Constitution that proposed a stronger federal government.
