One purpose of the executive branch is to command the armed forces. The executive branch, led by the President, is responsible for enforcing laws and has the authority to direct military operations.
The other options listed correspond to the roles of different branches of government:
- Interpret laws made by Congress is a function of the judicial branch (courts).
- Create and pass new laws is the role of the legislative branch (Congress).
- Oversee a system of courts is also part of the judicial branch.
Therefore, the correct answer is about commanding the armed forces.
