What public office can a naturalized citizen NOT hold?

A. County sheriff

B. Governor

C. President of the United States

D. U. S. Senator

The president of the United States cannot be a naturalized citizen - the actual phrase is that the president of the United States must be a "natural born citizen" - meaning that they must be born as citizens and not naturalized later (being born a citizen and naturalization are two ways of becoming a citizen)
