Which of the following is true about the voting age in the US?

Citizens must be at least eighteen years old to vote in the United States, as stipulated by the 26th Amendment to the Constitution, which was ratified in 1971. This amendment lowered the voting age from twenty-one to eighteen, ensuring that younger citizens who are legally considered adults can participate in the electoral process. Voting is a fundamental right, and the age was adjusted to reflect the responsibilities and rights granted to individuals once they reach adulthood. Other options state an age below or above the legal voting age but do not align with the current constitutional mandate that defines eighteen as the minimum voting age.
