"This feminist movement believes the key to understanding gender and identity is best understood by examining the intersection of key elements of identity like gender, race-ethnicity, sexual orientation, and economic class. This best describes which branch of feminism? "

Multiracial feminism

Explanation:

Multiracial feminism focused its approached on examining the patriarchal nature of different ethnicity which could lead to the situation that women felt in modern day.

Studies show that in general, almost every culture structured in a male dominant hierarchy, in which the women were expected were playing the supporting role. If we examine united states alone, we can found this in the majority of  ethnic groups (white, Black , Latina, and Asian).

One thing that might influence the percentage of female minorities in working force over the white women is the economic citizens. Poorer family tend to develop more need to get additional income which can be obtained by making both the wife and husband go out and get a job.
