Researchers Who Have Identified American Black-White Relations as a Form

Researchers who have identified American Black-White relations as a form of colonialism (when one group invades the other's territory and dominates it) , point the character of the relationship rather than geography. Which of the reasons below is one way that Whites exercise control in their ghetto "colonies"?

A) They exercise "indirect rule" by co-opting and controlling selected influential Blacks.
B) Whites sap the ghetto economically by overcharging Blacks for food (e.g. convenience stores) and other necessities and thus preventing them from acquiring lasting wealth.
C) Blacks are made to feel inferior by the constant barrage of negative stereotypes (e.g. all black males are felons) .
D) Their slave heritage preconditions Blacks to their inferior status.
