The correct answer is a presidential candidate must be a natural born citizen of the United States, a resident for 14 years, and 35 years of age or older.
Article 2 of the United States Constitution states that, in order for a person to serve as President of the United States, the individual must be a native citizen of the United States, at least 35 years of age and residing in the United States for at least 14 years.
If no candidate obtains more than 270 votes at the Electoral College, the 12th Amendment goes into effect and the United States House of Representatives decides who will be the new president and the United States Senate chooses the vice president.
