Which amendment gave women the right to vote?

The 19th Amendment is the correct answer because it was specifically ratified in 1920 to grant women the legal right to vote in the United States. This monumental change came after decades of activism and advocacy by women's suffrage organizations, which fought for equal voting rights. The passage of the 19th Amendment marked a significant turning point in American history, as it expanded democratic participation and recognized women's contributions to society.

The other amendments listed do not pertain to women's voting rights. The 15th Amendment, for example, focuses on prohibiting the denial of the right to vote based on race, color, or previous condition of servitude. The 16th Amendment addresses Congress's ability to impose income taxes, while the 24th Amendment prohibits poll taxes in federal elections. Each of these amendments deals with different aspects of voting rights and tax legislation, but none specifically grant women the right to vote, which is the pivotal achievement of the 19th Amendment.
