The 15th, 19th, and 26th Amendments to the United States Constitution all address voting rights.
- The 15th 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."
- The 19th Amendment, ratified in 1920, grants women the right to vote, prohibiting any U.S. citizen from being denied the right to vote on the basis of sex.
- The 26th Amendment, ratified in 1971, lowers the voting age to 18 years, ensuring that younger citizens have the right to vote.
Therefore, the correct response is voting rights.
