D. It shows that there were white citizens who treated African American citizens in unjust and humiliating ways.
Explanation:
Mildred D. Taylor's novel "Roll of Thunder, Hear My Cry" revolves around the story of a 9-year old girl named Cassie Logan. It deals with the theme of racism and how the blacks survived in white America.
In the given excerpt, Cassie narrates how she 'became' the slave of Lillian Jean and how she enjoyed being addressed<em> "Miz"</em> by<em> "her little colored friend"</em>. This shows how the whites see themselves as superior to the blacks while the blacks think it's normal for them to be treated as such.
Thus, this scene shows how white citizens’ treatment of African American citizens was unjust and humiliating.
