Answer: D. Parliamentary Democracy
Step-by-step explanation:
A Parliamentary Democracy is a system of government where the legislature is the Parliament and the head of the government is the leader of the party that has the majority in Parliament and becomes the Prime Minister.
A Constitutional Monarchy is most similar to this because this is the type of government that exists in most constitutional monarchies such as England and Lesotho. The monarch is the head of state but the head of government would be the Prime Minister and laws would be made by Parliament.
