Answer: B. Because of her actions, Miriam Mann became a target of the white women who supervised the West Computers.
The text in Chapter 6 of Hidden Figures discusses the events leading up to and following the "Battle of the West Area Cafeteria," in which the African American women working in West Computing at NASA Langley Research Center fought against segregation in the workplace. The chapter specifically mentions Miriam Mann, who was one of the leaders of the movement and faced backlash from the white supervisors for her actions. Therefore, the analysis in option B is the one that is best supported by the text.
