The correct description is:
The Reconstruction Amendments freed Black Americans, defined citizenship, reversed the Three-Fifths Compromise, and extended voting rights to Black American men, but put restrictions on voting rights and did not prevent the separate but equal doctrine.
This statement accurately reflects the impact of the Reconstruction Amendments (13th, 14th, and 15th Amendments) in abolishing slavery, granting citizenship and equal protection under the law, and extending voting rights specifically to Black men. However, it also acknowledges that subsequent laws and practices, such as Jim Crow laws and the "separate but equal" doctrine, imposed limits on the civil rights and voting rights of Black Americans.
