Answer:
a. The balance of power between the federal government and the state governments.
Step-by-step explanation:
Federalism is a political system in which power is divided and shared between a central government (i.e., the federal government) and individual states or provinces. This balance of power is typically outlined in a written constitution or other governing document that defines the roles and responsibilities of each level of government. Under a federal system, the federal and state governments have their areas of authority, such as taxation, law enforcement, and education. They are expected to work together to govern the country or region. This system is intended to ensure that power is not concentrated in one central authority but is instead distributed among multiple levels of government to promote a balance of power and protect the rights and interests of citizens.
