Which amendment to the U.S. Constitution is most closely associated with women's suffrage?

• A. First Amendment
• B. Fifteenth Amendment
• C. Twenty-Sixth Amendment
• D. Nineteenth Amendment

Answer: (D)

The main idea is identifying the amendment that guarantees women’s right to vote. The Nineteenth Amendment does exactly that by prohibiting any state or the federal government from denying the right to vote on the basis of sex, and it was ratified in 1920 to guarantee women nationwide suffrage.

The other amendments address different issues: the First Amendment protects freedoms like speech, religion, and assembly rather than voting rights; the Fifteenth Amendment prohibits denying the vote based on race, color, or previous condition of servitude but does not grant women the vote; the Twenty-Sixth Amendment lowered the voting age to 18, expanding suffrage by age rather than by gender.
