Answer:
B: State and National Governments
Step-by-step explanation:
Federalism is a system or mode of government, in which the power and responsibility of a geographical area are divided or shared between a central authority (The National Government) and the states (regions or provinces) with delimited self-governing authority. The Federal System varies from country to country, some give more power to the states and less to the government and vice-versa. Either way, this form of government tends to have a Constitution that serves as a guideline to regulate their acts and powers and to resolve any dispute.
