Answer:
[tex]\boxed {\tt A. \ Conduct \ foreign \ policy}[/tex]
Explanation:
The federal government can regulate and establish certain things that affect the whole nation.
So, they cannot control anything at the state or local level. Therefore, we can eliminate choices B, (regulate business within a state) C, (issue state licenses), and D (establish local governments).
The correct answer is A. conduct foreign policy. The nation's policy with other countries will affect the whole nation, so it is a federal government power.
