Cosmopolitan response to cases where cultures disagree

According to APPIAH, how does a cosmopolitan respond to  cases where cultures disagree about what’s right or wrong?

 

Question options:

AThe cosmopolitan acknowledges that there are many different cultural practices, and that in many cases different practices can be equally morally good. However, some cultural practices are morally wrong. One of the things cosmopolitans seek to do is to exchange ideas about which cultural practices are morally right and which are morally wrong.

 

BCosmopolitans navigate cultural variation by immersing themselves in it and celebrating it. They believe that once you have immersed yourself in a different culture, you will come to see that that culture’s moral practices are the morally right practices for it.

 

C“Cosmopolitanism” is another term for what Midgley calls “moral isolationism.” Cosmopolitans avoid cultural conflict by refusing to pass judgment on the practices of other cultures. They believe that no one can understand a culture they weren’t raised in, and judging without understanding is always wrong.

 

DThe cosmopolitan wants everyone to be his brother, but on the cosmopolitan’s terms. Cosmopolitans believe that the best way for us all to be citizens of the world is if we all move toward a single, globally shared culture, and so cosmopolitans try to peacefully encourage everyone to live in the exact same way (so there are no cultural differences anymore).
