The correct answer is A. federalism enables the state and the national government to share power

In a federal state, there is a central federal government with its own set of laws that apply to the whole federation. All laws not regulated by the federal government can be created by local state government for their own states as long as they aren't against the laws established by the federal government. Each state has their own laws to suit their needs.
