C) Southern states prevented African Americans from voting by charging them to do so.
Explanation:
Poll taxes were a popular method used by Southern states after the Civil War to stop African American men from voting. Poll taxes were used after African American men gained the right to vote with the 15th amendment to the US Constitution.
