Which of the following amendments extended voting rights to women in the United States?

The Thirteenth Amendment, ratified in 1865, abolished slavery and involuntary servitude in the United States. While it was a crucial step toward civil rights, it did not address voting rights or women’s suffrage specifically.

Ratified in 1868, the Fourteenth Amendment granted citizenship to all persons born or naturalized in the United States and provided equal protection under the law. However, it did not explicitly extend voting rights to women, focusing instead on issues related to citizenship and equality.

The Fifteenth Amendment, ratified in 1870, prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude." While it advanced voting rights, it did not include women, thereby leaving a gap in suffrage for half the population.

Ratified in 1971, the Twenty-Sixth Amendment lowered the voting age to 18 years. While it expanded voter access, it did not pertain to the issue of women's voting rights, which had already been established by the Nineteenth Amendment.
