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.

  The so-called unitary government presents itself as a form of state in which power is rooted in a single interstate entity. In other words, it is the centralized state whose parts that integrate them are linked to it, thus having no autonomy.
