Final answer:
In a unitary system of government, power is centralized, and districts are under the control of the national government. The correct answer is C. Districts can be made and abolished by the national government.
Step-by-step explanation:
In a unitary system of government, the central government holds the majority of governing power and can create or abolish districts at its discretion. This means that local or regional governments, such as districts, are under the direct control or influence of the national government and do not have autonomous power. They carry out instructions from the central government and are not independent entities. Accordingly, the correct answer to the question on how government authority is distributed in a unitary system of government is C. Districts can be made and abolished by the national government.
Unitary systems are characterized by a strong central government with the power to grant or withdraw authority to local levels as it sees fit. Unlike federal systems where the constitution allocates power between national and state governments, or confederations where authority is decentralized, a unitary system concentrates power in the national government.
