A federal system of government exists when power is shared between a central, federal body, and smaller entities such as states. The Founders chose this because they wanted to protect state and individual rights while making sure that the country had a strong central power.
The policy described is domestic policy as it takes place within U.S. borders. The answer can't be foreign policy as that would be policy applying outside the country. Neither can it be either of the other two because the question has nothing to do with the functions of trade or judiciary "law making" via the interpretation powers granted to the judicial branch.
