A.Powers are divided between the federal government and the states.

Explanation:

Federalism is a political system in which political organizations (states, provinces) or groups come together to form a broader organization, such as a Central State. In the federalist system, the states that integrate it maintain autonomy.

A good example of federalism is the United States of America. The states unite to form the central system, but they have the autonomy to define subjects of diverse natures, for example, creation of laws, definition of public policies, creation and collection of taxes, etc. That is, in the US, powers are divided between the federal government and the states, so the answer is the letter A.
