Which amendment granted women the right to vote in the US?

The 19th Amendment to the United States Constitution is the amendment that granted women the right to vote. Ratified on August 18, 1920, it marked a significant victory in the women's suffrage movement, which had been advocating for women's voting rights for many decades. This amendment states that the right to vote shall not be denied or abridged on account of sex, thus prohibiting any discriminatory voting practices against women. The passage of the 19th Amendment was the culmination of a long struggle by suffragists and is a pivotal moment in American history, representing a significant expansion of democratic principles and civil rights in the U.S.

The other amendments listed do not pertain to women's voting rights. The 16th Amendment relates to income tax, the 18th Amendment instituted Prohibition, and the 17th Amendment established the direct election of U.S. senators. These amendments serve different purposes within the Constitution and do not address the issue of voting rights for women.
