Urbanization.

The process by which large numbers of people become permanently concentrated in relatively small areas, forming cities.
The Brown vs. Board of Education ruling and the Civil Rights Act of 1964 both aimed at increasing opportunities for black citizens in America.
The Brown vs. Board of Education ruling stated that "separate but equal" schools for black and white citizens violated the 14th amendment of the US Constitution. This resulted in black citizens getting the opportunity to attend public high schools and colleges that gave them better opportunities for success.
The Civil Rights Act of 1964 was a law that made it illegal to discriminate against an individual applying for a job based on their race, sex, gender, etc. This ensured that black citizens had a better opportunity to gain emplyoment.
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.
