Correct Answer:
B. Constitutional Monarchy
The correct answer is Constitutional Monarchy. Norway is a constitutional monarchy with a parliamentary system. This means the country has a monarch (King Harald V) who serves as the ceremonial head of state, while the Prime Minister is the head of government, and executive power is exercised by the cabinet.
Norway is not a presidential system, and while it is a democracy, "Democratic system" is too vague compared to the precise term "Constitutional Monarchy."
