Final Answer:
The form of government described is B) Unitary government. Thus the correct option is B.
Step-by-step explanation:
In a unitary government, ultimate governmental power is highly centralized, with authority residing in a single central agency. This central agency has the authority to delegate specific powers to smaller units or administrative divisions. The key characteristic is the concentration of power at the national or central level, and any powers granted to lower levels are at the discretion of the central government.
Unlike federal systems (option A), where powers are constitutionally divided between a central government and subnational entities, unitary governments provide a more centralized and consolidated structure. This centralization often leads to a more efficient decision-making process but can also raise concerns about potential lack of local autonomy.
Unitary systems are commonly found in countries seeking strong central control and swift policy implementation, offering a clear contrast to confederal systems (option C), where independent states retain significant authority. Furthermore, the unitary model is distinct from parliamentary systems (option D), where executive and legislative branches are interconnected but not necessarily characterized by centralized power. Thus the correct option is B.
