The correct answer is C) 35; 30.
You pick up a newspaper and are disappointed to find that part of the headline is missing. It reads, "Youngest candidates ever! The presidential candidate is 35; candidate for Senate is 30."
Do you want to be President of the US or Senator? Well, here you have the requirements.
The requirements to be President of the United States are: he or she must be a natural-born citizen of the US, 35 years old or older, and being a resident for fourteen years in the country.
The requirements to be Senator are: they must be 30 years old, at least; being a citizen of the United States for nine years before the election, and the candidate must be an inhabitant of the state he/she wants to represent.
