The 15th, 19th, and 26th Amendments all pertain to voting rights.
- The 15th Amendment prohibits denying a citizen the right to vote based on "race, color, or previous condition of servitude."
- The 19th Amendment guarantees women the right to vote.
- The 26th Amendment lowers the voting age to 18, ensuring younger citizens can participate in elections.
So the correct answer is voting rights.
