Step-by-step explanation:
Among the options given about the amendments to the Constitution concerning voting rights, the true statement is that only citizens 18 and older can vote. The Twenty-Sixth Amendment, ratified in 1971, lowered the voting age from 21 to 18 years old.

The history of voting rights in the United States has been a progressive journey of expanding suffrage.
This includes removing restrictions based on property ownership, race (with the 15th Amendment), gender (with the 19th Amendment), poll taxes (with the 24th Amendment), and eventually age. Despite these advancements, the struggle against voter suppression and ensuring fair access to voting continues. The correct answer is Only citizens 18 and older can vote.
