To accurately compare the advantages of unitary and federal governments, the best response would be:
Federal governments offer more personal freedom. Unitary governments have less internal division.
This statement reflects a common perspective on the distinctions between unitary and federal systems. Federal governments often allow for more local autonomy and personal freedoms due to their structure, which distributes power across various levels of government. Conversely, unitary governments, which centralize authority, may handle internal divisions more easily but might limit personal freedoms due to the concentration of power.
Other options present oversimplified or inaccurate views of the differences between the two systems.
