C. federation

A federation is a political entity where partially self-governing provinces, states, or other regions that are unified, agree to be governed under one central authority (the government), which is often elected by its member. Federations tend to have a federalist Constitution as well in which the scope of the power of both levels of government is outlined. The United States and Canada are examples of a federation.
