In what way were both the universal declaration of human rights and the postwar push the civil rights reactions to the war

The Universal Declaration of Human Rights, established after World War II, outlined rights that all individuals should have regardless of where they live. This was a direct result of the war, as the genocide conducted by Nazi Germany severely limited the rights of individuals all over Europe. The systematic killing of individuals showed that a list of rights that all individuals should have was needed.

The Civil Rights was also a reaction to World War II. African-Americans served bravely during this war, helping to liberate millions of Europeans. However, when returning home, they were continually mistreated due to the discriminatory policies in the Deep South. African-Americans who served in the war felt that they should have victory over discrimination in the US. This campaign became known as the Double V Campaign.

I believe the answer is C. all immigrants were forced to sign a statement supporting the tolerance  I'm not 100% sure though but it seems like the best option
