To be president, a person must be

• A. A natural born citizen
• B. 45 years old
• C. A legalized citizen
• D. 40 years old

Answer: (A)

Eligibility to be president is defined by the Constitution. The key rule here is that the president must be a natural-born citizen. That means you are a citizen at birth—typically someone born in the United States or someone born abroad to U.S. citizen parents under certain conditions. This requirement is meant to ensure a direct, longstanding allegiance to the United States from birth.

The other possibilities don’t fit because the Constitution sets age and citizenship status differently. The presidency requires at least 35 years old, and it also requires residency in the United States for a specified period. Being older (like 40 or 45) isn’t the issue here, and being a naturalized citizen—someone who became a citizen later—does not satisfy the natural-born requirement.
