Which shows the power of a unitary government

Question

States have equal powers with each other
States have more power than federal government
States can establish rules that cities have to follow
States can vote on the laws of the national government

Answer 1

A unitary government is characterized by a central authority that holds the majority of power, with any administrative divisions (like states or provinces) exercising only powers granted to them by the central government. In the context of your statements, the one that reflects the power of a unitary government is:

States can establish rules that cities have to follow.

In a unitary system, the central government can delegate powers to local governments (like cities), but it retains the authority to set rules and guidelines for those subdivisions. The other statements about states having equal powers, more power than the federal government, or voting on national laws are not consistent with the principles of a unitary government.
