The correct answer is C) has restrictions on the powers of its officials.
A "limited government" is a government that has restrictions on the powers of its officials.
Constitutional law limits the government to intervene in the lives of the citizens. The United States is a good example of a limited government. That is why the system of checks and balances is so important to the United States.
The system of checks and balances has helped the United States government to maintain a balance of powers so neither branch can dominate the other or abuse in the application of its powers. The President of the United States -the executive branch- has the power of vetoing laws that Congress wishes to pass. That is its check on the legislative. But the legislative can override the President's veto by a two-thirds vote in the House of Representatives and the Senate. Meanwhile, the Judicial branch checks both branches by declaring laws unconstitutional.
