C) Dictatorship
Explanation:
B, C, D, can all be argued to be government under one person's control, but usually the answer is C) Dictatorship.
Why it's not A):
A can be broken down into two sub-categories, direct democracy, and indirect democracy. Direct Democracy is typically practiced in a smaller term when it affects a certain, but smaller group of people. In DD, each person is allowed one vote, and the majority rules on provisions. Indirect Democacy, on the other hand, is a bit different. ID is a practice in which people elect representatives, who in turn vote for issues based on what they promised voters. The United States of America today typically practice Indirect Democracy within politics.
Why it's not B:
B usually evolves into a Dictatorship, but it does not start out as one. The foundng principle is to give collective power to the workers in general, and allow them to control the means of production. However, in history, time and time again this type of government structure fails, and leads to dictatorships (one person in complete control). Examples can be when power is given to the people during uprisings, including Pol Pot's grasp for power, the Bolshevik's rise, and others, but generally leads to a figure head that takes complete control (Josef Stalin in the case of Bolshevik's, and Pol Pot in the case of Vietnam). However, in the end, socialism was not meant to give one person complete control, but rather is an unintended consequence (further showing that Socialism doesn't work).
Why it's not D:
Typically when talking about a monarchy, one suggests the whole royal family as holding the power. Usually the queen or king typically holds the majority of the power, but each person in the royal family have a fairly major role to play in the politics of the nation. Monarchy's power can be attainable by only one person, but typically is shared within the family and passed down through the generations, suggesting that it is not exactly "one person in complet control".
