A. Many minorities were unable to vote due to the poll tax.

Explanation:

The fifteenth amendment of US constitution protects the citizens right to vote, regardless of their race or the color of skin. After the civil war US constitution was amended, the thirteen amendment abolished the slavery and the fifteenth amendment gave the slaves rights of US citizens. But the states still tried to discriminate with the former slaves through poll taxes, literacy tests, white primary system and intimidation. The poll tax worked by charging the slaves with a poll tax while white people were exempted due to grandfather clause.
