Answer:
D. governmental power is shared
Explanation:
In a Federal state, the power within the government typically shifted into several smaller regions. Each regions will be given with the power to independently regulate themselves (creating legislations, proposing government programs, etc), In United States, we refer to this as States government.
On top of the states government, Federal state established Central government. The central government has authority over the states government and will be responsible to create regulations that affected a nation as a whole rather than one individual states.
