Answer:
B.Difference & Class
Explanation:
Racism involves Differences and Class. Anything that individuals with a racist mindset can target as permanent differences or differences that widely seperate them from those they target would be considered racism factors. These permanent differences can include skin color, ancestry, culture, etc. While other unbridgeable differences would mainly be in regards to Class, meaning the socioeconomic status of an individual, usually divided between high, middle, and lower class populations.
