What is a common requirement for members of Congress regarding age?

Members of Congress must adhere to specific age requirements that are outlined in the U.S. Constitution. For the House of Representatives, a member must be at least 25 years old. For the Senate, the age requirement is higher, with members needing to be at least 30 years old. Additionally, a member of the Senate must be at least 35 years old to ensure they have sufficient experience and maturity for the role. Since all these age requirements must be satisfied by their respective chambers, the correct answer encompasses all of them, indicating that each stated age minimum is a common requirement for those serving in Congress. This understanding highlights the distinct criteria that reflect the intended responsibilities expected of representatives and senators.
