Which amendment grants the right to vote to women?

The 19th Amendment is the one that grants women the right to vote in the United States. Ratified in 1920, it states that the right to vote shall not be denied or abridged on account of sex. This amendment was a significant milestone in the women's suffrage movement, which fought for women's rights to participate in politics and elections.

In contrast, the other amendments mentioned do not pertain to women's voting rights. The 15th Amendment, for example, addresses voting rights regardless of race, color, or previous condition of servitude but does not specifically mention gender. The 24th Amendment prohibits the use of poll taxes in federal elections, aiming to remove financial barriers to voting but not specifically focused on women's suffrage. Lastly, the 26th Amendment lowers the voting age to 18, again not related to gender. Thus, the 19th Amendment distinctly recognizes and affirms women's right to vote, making it the correct answer to the question.
