Final answer:
The Constitution mandates that members of the House of Representatives must be at least 25 years old and those in the Senate must be at least 30 years old, reflecting different maturity and experience levels expected for each house.
Step-by-step explanation:
The minimum age requirements for members of Congress as outlined in the Constitution vary between the two houses. In the House of Representatives, members are required to be at least 25 years old, have been U.S. citizens for at least seven years, and live in the state they represent. On the other hand, to serve in the Senate, one must be at least 30 years old, have been a U.S. citizen for nine years, and be an inhabitant of the state they seek to represent. The Constitutional requirements ensure that members of Congress have a certain level of maturity and experience, while also maintaining a connection to their respective states. As per the options outlined in the student's question, the correct answer is that one must be at least 30 to serve in the Senate which can be found in Article I of the U.S. Constitution.
