The correct answer is D.
The concept of limited goverment refers to public authorities which are empowered by law, whose powers are the ones granted by the country's Constitution and can never be excedeed.
In the US, the Tenth Amendment to the Constitution describes the powers which are delagated to the federal goverment. Other legal documents, such as the First Amendment, include the fundamental civil rights that need to be guaranteed to US citizens, such as freedom of speech or freedom of assembly, and these rights cannot be violated by any goverment that comes to power, because the actions of such goverment are limited by the provisions of the Constitution. In opposition, unlimited goverments can more likely violate fundamental legal provisions, such as civil rights, if compared to limited ones.
