What is the age requirement to serve in the Arizona State Legislature?

The correct age requirement to serve in the Arizona State Legislature is that candidates must be at least 25 years old to serve in the Senate and at least 21 years old to serve in the House of Representatives. This means option C does not accurately reflect the correct age requirement, as it states 18 years old for the House, which does not meet the established standard.

To clarify, option A correctly states that an individual must be at least 21 years old for the House, adhering to Arizona's constitutional criteria. This means that it correctly outlines the minimum age for one chamber. Meanwhile, option B inaccurately assigns a higher age for the House and does not meet the age requirements originally set forth in the Arizona Constitution. Finally, option D suggests even higher age limits for both houses, which is not accurate considering the state's established laws.

Understanding these age requirements is essential as they ensure that those entering the legislature have a certain level of maturity and life experience, which is expected to translate into effective governance and representation for the citizens of Arizona.
