What is the term for a system of government where citizens vote in regular elections to choose their representatives?

The term "Democracy" refers to a system of government in which the power lies with the people, allowing them to participate in decision-making processes, primarily through the act of voting. In a democratic system, citizens have the right and opportunity to vote in regular elections to choose their representatives. This process ensures that the government reflects the will of the population, as elected officials are accountable to the voters and must consider their needs and interests.

In contrast, other forms of government listed, such as Monarchy and Autocracy, do not primarily emphasize citizen participation via elections. Monarchies can be hereditary, where leaders are born into their roles rather than elected, while autocracies center power in a single ruler without popular elections or choices. Theocracies intertwine religious authority with governance, often prioritizing religious leadership over democratic processes. Thus, "Democracy" stands out as the correct term for a system defined by citizen voting in regular elections.
