Which amendments are specifically associated with voting rights?

The correct choice identifies the amendments that have played a crucial role in expanding and protecting voting rights in the United States.

The 15th Amendment prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude," thus ensuring that African American men and other marginalized groups could participate in the electoral process.

The 19th Amendment grants women the right to vote, marking a significant step forward in gender equality and enfranchising half the population.

The 24th Amendment eliminates poll taxes in federal elections, removing a financial barrier that was used to restrict voting, particularly among poorer citizens and African Americans.

The 26th Amendment lowers the voting age to 18 years, acknowledging that young people, particularly those affected by military service, should have a voice in their governance.

This collection of amendments highlights a progressive expansion of voting rights throughout American history, making choice C the correct answer. The other options do not focus specifically on amendments that directly address voting rights in a comprehensive manner.
