Ethnocentrism NS question

[basophilic]

Which of the following groups will feel the LEAST amount of ethnocentrism?
B. A group with a high socioeconomic status
D. A group that has alternated having political representation with another group.

I don't understand why the answer is B. Never seen this implied on TPR addendum, Wikipedia, or Khan videos. Also, I don't understand why D is wrong; if Group A is willing to alternate between members of Group A and members of Group B for political representation (and vice versa), then why wouldn't there be reduced ethnocentrism b/w A and B?

Because this question asks you to rank answers (includes the word least), could you post the other options, too?

Because this question asks you to rank answers (includes the word least), could you post the other options, too?

A. A group who has just entered an armed conflict with another nearby group
C. A group in which members wearing similar clothing is encouraged

I felt these were straightforward to eliminate and hence didn't included in OP. I don't understand the negative correlation b/w SES and degree of ethnocentrism and why D is wrong.

I honestly don't see why B is correct, and I think D is vaguely written. You interpreted D as people willingly switching political representation, but I interpreted it as Group A having representation and Group B as not having it, when before this was not the case. A lack of representation might spawn animosity between the groups, leading to ethnocentrism. I guess I might choose B by process of elimination, but overall I think the answer choices are poorly written.
