What is a primary function of the executive branch?

The primary function of the executive branch is to enforce laws. This branch of government is headed by the President, who is responsible for ensuring that the laws created by the legislative branch are implemented and followed. The executive branch includes various agencies and departments that manage the day-to-day enforcement of laws and regulations, handling everything from law enforcement to public policy administration. This role is crucial for maintaining order and ensuring that laws serve their intended purpose within society.

In the context of this question, the other choices relate to functions of different branches of government. The legislative branch is responsible for writing laws, and the judicial branch interprets the laws. The choice of 'repeal laws' does not accurately reflect any specific branch's primary function but rather involves a legislative action to annul existing laws. Therefore, the enforcement of laws clearly stands out as the essential and defining role of the executive branch.
