Which amendment provides citizens the right to vote without paying a tax?

The correct choice is rooted in the historical context of voting rights in the United States. The 24th Amendment, ratified in 1964, specifically prohibits the use of poll taxes in federal elections. Poll taxes were fees that individuals had to pay to be able to vote, and they were seen as a barrier that disenfranchised poorer citizens, particularly African Americans and poor white citizens.

By abolishing poll taxes, the 24th Amendment aimed to ensure that voting is accessible to all citizens, regardless of their economic status. It is a significant step in the broader civil rights movement which fought against various forms of discrimination and disenfranchisement.

In contrast, other amendments mentioned, such as the 15th Amendment, focus on prohibiting voting discrimination based on race; the 19th Amendment grants women the right to vote; and the 26th Amendment lowers the voting age to 18. While all these amendments play crucial roles in expanding voting rights, it is specifically the 24th Amendment that addresses the prohibition of poll taxes in voting, thus securing the right to vote without the requirement of paying a tax.
