Answer:
The correct answer is c)
Step-by-step explanation:
Federalism is a system of government that is characterized for having both a central government and local governments with a large degree of sovereignty over their affairs. Federalism is the preferred form of government in countries where there's significant differences between regions. Generally speaking, the federal government deals with affairs that are important to all the residents of the federation, while leaving local and regional issues to local governments. This arrangement is beneficial for the latter, because it does not require citizens to be ruled by majorities from different regions and with different interests, which would happen under a state where local affairs were decided by a single central government.
