The correct answer is D. Its local governments cannot be abolished by the central government.
Step-by-step explanation
A federation is a name in which a set of entities, institutions, or others that have relative autonomy and are related at the same time are known. At present, there are several countries whose form of government is the federation made up of States that have a marked autonomy concerning a control center. On the other hand, there is the unitary state, which is the system of government opposed to the federation because, in it, power is concentrated in a single center of authority that extends its actions throughout the entire territory. Therefore, the correct answer is D. Its local governments cannot be abolished by the central government because in the confederation a local government does not depend on the central government but rather has autonomy.
