Answer:
The correct answer is B. A government in which one person holds supreme power within the state is called an autocracy.
Step-by-step explanation:
Autocracy is a system of government exercised by one person or a small group of people, possessing unlimited power, being beyond any social control. The main distinguishing features of autocratic state systems is the concentration of all state power in the hands of an individual or group, ruling through a monolithically and hierarchically organized apparatus over a society devoid of legal forms of influence on the appointment and change of rulers as well as on programs and methods of governance.
Today, it is often synonymous with the words despot and dictator, although these terms are used in a variety of situations. Autocracy has also historically been associated with a monarchy in which all power in the country lies with the king. But unlike the monarchy where power is inherited, autocracy can also come to power through elections.
