sasho [114]

Answer:

B. Elect their government officials.

Explanation:

A republican form of government is one where the people are involved in electing their government officials who became their representatives in governing the nation. The citizens are responsible for choosing who their leaders are, and through that, the government's power comes from them.

This form of government was used in Rome where the citizens were allowed to elect their government officials. These elected officials rule on the people's behalf and become the 'voice' for the people.

Thus, the correct answer is option B.
