Answer:
B. Monarchy
Explanation:
A monarchy is a country that is ruled by a monarch, and monarchy is this system or form of government. A monarch, such as a king or queen, rules a kingdom or empire. In a constitutional monarchy, the monarch's power is limited by a constitution. But in an absolute monarchy, the monarch has unlimited power.
Monarchy is a form of rule in which there is a single head of state, a monarch, with the title of King, Queen or similar titleholder. The head of state usually inherits the title through rules of descendency as a member of a specific royal family and holds his or her office for life.
There are lots of different examples of monarchy in the world today. Constitutional monarchies have a hereditary head of state, but are to all intents and purposes democracies.
Some examples of this are the UK, Netherlands, Spain and Sweden. Monarchs in other countries have more power, for example in Saudi Arabia.
