Answer:
3). Mama losing her job.
Step-by-step explanation:
Mildred D. Taylor's text titled 'Roll of Thunder, Hear My Cry' primarily focuses upon the central conflict of 'racist slurs and racial discrimination' that caused the blacks to undergo severe injustice and oppression. In the story, the Logans farmers suffer this oppression and battle for their rights. Mary Logan or Mama believes that such abuse must not be accepted and thus, the conflict escalates when she loses her job as the protest becomes stronger and more intense. Thus, option 3 is the correct answer.
