What is the minimum age to become a President of the United States?

The minimum age to become President of the United States is established in the U.S. Constitution, specifically in Article II, Section 1. The Constitution clearly states that a person must be at least 35 years old in order to be eligible for the presidency. This requirement reflects the Founding Fathers' intention to ensure that candidates for this significant office possess a certain level of maturity and life experience. Hence, the correct choice indicates that the legal minimum age is indeed 35 years old.
