A. two advantages of a unitary government are that it standardizes rules for the countrt and reduces conflicts between different levels of government

Explanation:

    Unitary government is formed by a single state, with a unity of internal political power, whose exercise occurs centrally; any degree of decentralization depends on the agreement of the central power - eg, Italy, France and Portugal.
