Answer:
A. Democratic reforms.
Explanation:
Human rights has always been tied to the democratic party, so this answer just makes the most sense to me.
The other answers don't make sense because while the UN is connected to human rights, the sentence doesn't check out for it. Supporting human rights does help the UN, but it doesn't really support it. Military allies also makes sense, but again, human rights doesn't support them. The U.S. economic interests doesn't make sense either, because human rights, while needed, are often expensive for the government, which is why they won't do much.
