Which amendment granted the right to vote to women in the United States?

The 19th Amendment is the correct answer because it specifically states that the right to vote cannot be denied or abridged on the basis of sex. Ratified in 1920, this amendment marked a pivotal moment in American history, as it granted women the legal right to vote, following decades of activism and struggle for women's suffrage.

The 15th Amendment primarily addresses voting rights but focuses on prohibiting the denial of the vote based on race, color, or previous condition of servitude, rather than gender. The 21st Amendment deals with the repeal of Prohibition and does not pertain to voting rights. The 24th Amendment addresses the prohibition of poll taxes in federal elections, further preventing financial barriers to voting, but it does not specifically grant voting rights to women. Each of these amendments plays a significant role in the broader context of voting rights in the United States, but the 19th Amendment is uniquely designated for women's suffrage.
