The correct answer is C) confederate.
Confederate is an example of a geographic way to classify governments.
A confederation is formed when a group of people or in this case, states, create an alliance. Each of the states in the alliance governs itself and participate with the other states in causes that benefit all of them. The best example we have in America in the Confederated States of the South that defended their slave system in the plantations to grow crops. They depended so much on slaves.
