Final answer:
In a unitary system of government, local offices must follow the decisions made by the central government and do not have equal power or the ability to veto central decisions.option C is correct answer.
Step-by-step explanation:
In a unitary system of government, the central government holds the predominant power when compared to local governments. Local and regional offices do exist; however, they operate under the authority or control of the central government, with the latter having the ability to delegate or withdraw powers as it deems necessary. This ensures consistency of laws and policies but may also lead to centralization issues or disconnect with local needs.
Countries like the United Kingdom have moved towards devolution, which is the delegation of certain powers to regional governments, making their system somewhat less centralized. On the other hand, federal systems like the United States, provide both the central and regional governments with a degree of autonomy, ensuring a balance of power and reducing the chance of central tyranny.
To directly answer the student's question, in a unitary system of government, local offices C. must follow decisions made by the central government. They do not have equal power with the central government nor the ability to veto its decisions, but rather they serve to implement the central government's policies at the local level.
