Which of the following is a function of government?

Maintaining public order is a fundamental function of government as it ensures that society operates smoothly and safely. This involves establishing laws and regulations that govern behavior, thereby reducing the occurrence of conflict and crime. A government achieves this by employing various institutions, such as law enforcement, the judiciary, and correctional facilities, to enforce laws and adjudicate disputes. The presence of public order allows citizens to coexist in a stable environment, which is essential for the functioning of any society.

Other options present ideas that do not align with the primary roles of a government. For example, promoting individual wealth accumulation is not a specific governmental function; instead, government may create conditions that allow for economic activity. Similarly, controlling all aspects of life suggests an authoritarian approach that limits personal freedoms, which is not characteristic of democratic governments. Lastly, eliminating competition contradicts the principles of a market economy, where competition can be beneficial for innovation and consumer choice, and is generally not a goal of legitimate governments.
