Which of the following is a qualification to vote in Arizona?

In Arizona, one of the primary qualifications to vote is that an individual must be at least 18 years old and registered to vote. This requirement ensures that voters have reached the legal voting age, which is a standard practice across the United States. Additionally, registration allows the state to maintain an accurate and up-to-date voter roll, ensuring an organized electoral process.

The other options do not align with the qualifications set for voting in Arizona. Being a resident alien does not qualify someone to vote in elections, as voting is restricted to U.S. citizens. Similarly, a college degree is not a requirement for voting, and property ownership is also not a stipulation to participate in the electoral process in Arizona. Thus, being at least 18 years old and registered encompasses the critical elements necessary for an individual to legally cast their vote.
