Which amendment states all women have the right to vote?

• A. Amendment 18
• B. Amendment 19
• C. Amendment 20
• D. Amendment 21

Answer: (B)

Expanding who can vote is the idea. The amendment that guarantees women's suffrage states that the right to vote shall not be denied or abridged on account of sex. It was ratified in 1920, marking nationwide protection of voting rights for women after a long suffrage movement. Before this change, many states allowed women to vote, but not uniformly across the nation. This amendment focuses specifically on gender and ensures women can participate in elections nationwide, rather than leaving the issue to individual states. Other amendments address different topics, so this one is the landmark for women’s voting rights.
