Which amendment grants women the right to vote?

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

Answer: (B)

The idea being tested is voting rights for women and how a constitutional change made that right universal across the United States. The amendment that guarantees women the right to vote states that the right to vote cannot be denied or abridged on the basis of sex. This language was ratified in 1920 after a long and sustained push by the women's suffrage movement, which included decades of organizing, lobbying, and activism at both state and national levels. Once enough states ratified it, the change became part of the Constitution, ensuring women could vote in all elections nationwide rather than just in certain states.

This contrasts with the other amendments in the list: one established Prohibition, another set the dates for when the president and Congress begin their terms, and the last repealed Prohibition. None of those address voting rights based on gender, so they do not fit the question as directly as the amendment that secured women’s suffrage.
