D. Many Anti-Federalists refused to support the Constitution unless the Bill of Rights was added

Explanation:

Fearing that the new proposed Constitution would give too much power to the government and did not specifically protected individual rights from abuses of the government, many Anti-Federalists refused to support it unless a Bill of Rights was added.

Finally, they achieved their purpose and the first ten amendments to the Constitution were created in 1791. This Bill of Rights, still valid nowadays, guarantees people's right and to express themselves, to practice the religion they want, to enjoy a speedy and public trial by an impartial jury in criminal prosecutions, to be free from unreasonable government intrusion in their homes through the requirement of a warrant, among others.
