Which amendment granted women the right to vote?

The 19th Amendment to the United States Constitution is the amendment that specifically granted women the right to vote. Ratified in 1920, it states that the right to vote shall not be denied on the basis of sex. This amendment was the culmination of decades of activism and struggle by women's suffrage advocates who fought for gender equality in voting rights.

The other amendments listed do not pertain to women's voting rights. The 21st Amendment repeals the prohibition of alcohol, the 22nd Amendment limits the number of terms a president can serve, and the 15th Amendment prohibits denying a citizen the right to vote based on race, color, or previous condition of servitude. None of these directly involve the voting rights of women, making the 19th Amendment the correct answer.
