A) Only citizens 18 and older can vote CORRECT This is the correct answer because the 26th Amendment guarantees that no state can deny the right to vote to citizens who are 18 years of age or older. The 15th, 19th, and 24th Amendments further protect voting rights by prohibiting discrimination based on race, sex, and poll taxes. Therefore, the only constitutional requirements for voting are U.S. citizenship and being at least 18 years old.
B) Any resident can vote INCORRECT This option is incorrect because voting rights are reserved for U.S. citizens. Non-citizens, including legal permanent residents, are not allowed to vote in federal elections. While some local elections may allow non-citizens to vote, this is not a constitutional right and does not apply to all residents.
C) Only landowners can vote INCORRECT This option is incorrect because property ownership requirements for voting were common in the early United States but were abolished by the mid-19th century. The Constitution does not require property ownership to vote, and such requirements would violate the principle of universal suffrage.
D) Only men can vote INCORRECT This option is incorrect because the 19th Amendment, ratified in 1920, prohibits denying the right to vote on the basis of sex. Women have the same voting rights as men, and any law that restricts voting to men would be unconstitutional.
E) Only white men can vote INCORRECT This option is incorrect because the 15th Amendment prohibits denying the right to vote based on race, color, or previous condition of servitude. This amendment was ratified in 1870 and ensures that African American men, and later all citizens regardless of race, have the right to vote.
F) Only taxpayers can vote INCORRECT This option is incorrect because the 24th Amendment, ratified in 1964, abolished poll taxes in federal elections. States cannot require payment of a tax as a condition for voting, as this would disenfranchise low-income citizens.
G) Only college graduates can vote INCORRECT This option is incorrect because the Constitution does not impose educational requirements for voting. The Supreme Court has ruled that literacy tests and educational qualifications for voting are unconstitutional, as they violate the equal protection clause of the 14th Amendment.
