The most successful objection the antifederalists raised against the proposed constitution was: a. the absence of a bill of rights that would protect individuals. b. the lack of term limits on members of the legislative and executive branches. c. the necessary and proper clause gave congress too much leeway to extend its authority. d. the strong provisions for judicial review would turn the supreme court into the most powerful branch of the government.

A. Absence of bill of rights is the correct answer.

Explanation:

The Anti Federalists were the politicians who were against the US constitution that was adopted in 1787. They considered the constitution to be giving too much power to the central government and they were afraid to single national government. Patrick Henry, James Winthrop and George Mason were some of the famous Anti federalists. They were afraid  because the states were given more power in Articles of Confederation and Perpetual Union while it wasn't so in the new constitution. Their influence led to the passage of bill of rights.

the answer is c, all the other options are things they are known for.
