Which group of citizens does not have to pay a poll tax to vote?

The choice indicating that citizens eighteen (18) and older do not have to pay a poll tax to vote is correct because the 24th Amendment to the U.S. Constitution, ratified in 1964, prohibits the use of poll taxes in federal elections. This amendment ensures that no citizen, regardless of age (as long as they meet the minimum voting age), should have to pay a tax in order to exercise their right to vote. Prior to the amendment, poll taxes were often used as a means to disenfranchise poorer citizens, particularly in the South.

The other options, while acknowledging aspects of voting, do not directly relate to the abolition of the poll tax. For example, stating that either gender or any citizen can vote does not address the restriction or requirement of a poll tax. Similarly, referencing male citizens of any race does not consider the broader context of voting rights that includes all citizens over eighteen and highlights the fundamental principle of eliminating barriers to voting based on financial requirements.
