In which system of government are citizens responsible for electing their representatives?

The correct choice refers to a system of government where citizens play an active role in choosing their representatives to make decisions on their behalf. In this context, a republic specifically emphasizes the role of elected officials, who are accountable to the citizens, ensuring that the government operates based on the will of the people.

While democracy also involves citizen participation in electing representatives, the term is broader and can encompass different forms of governance, including direct democracy where citizens vote directly on issues. A republic is a form of democracy that specifically denotes a system where representatives are elected rather than being appointed by hereditary means or ruled by a single monarch.

In contrast, a theocracy is a system where religious leaders control the government, and citizens typically do not have a role in electing representatives. Monarchy, particularly absolute monarchy, involves hereditary rule, where power is concentrated in the hands of a single ruler, making citizen elections irrelevant.

Therefore, the essence of a republic lies in its foundation of elected representation, making it the most fitting answer for a system where citizens are responsible for electing their representatives.
