Answer: A
. The Department of Veterans Affairs will use its authority to decide how to implement the law effectively.
Step-by-step explanation:
The duty of the Legislature is to pass laws and the duty of the Executive is to enforce those laws. When Congress therefore passes a law, the relevant executive agency is to begin the process of implementing the law.
In this instance involving transition programs for veterans of the Afghanistan War, the relevant executive agency is the Department of Veteran Affairs. Once this becomes legislation, the Department should use its authority to decide how to implement the law effectively.
