Which Constitutional amendment gives women the right to vote?

The Nineteenth Amendment is the correct choice because it explicitly granted women the right to vote in the United States. Ratified in 1920, this amendment states that the right to vote cannot be denied or abridged on account of sex. The movement for women’s suffrage gained momentum throughout the late 19th and early 20th centuries, and the passage of the Nineteenth Amendment was a significant milestone in securing equal voting rights for women.

Other amendments listed do not pertain to women's voting rights. The Twelfth Amendment mainly deals with the electoral process for the President and Vice President. The Fifteenth Amendment prohibits the denial of voting rights based on race, color, or previous condition of servitude, and the Twenty-Fourth Amendment prohibits poll taxes in federal elections. While each of these amendments addresses important aspects of voting rights in the U.S., none specifically affirms the right to vote for women as the Nineteenth Amendment does.
