Answer:
C). Racial and ethnic categories do not have equal social standing.
Explanation:
As per the question, the United States would not be considered truly pluralistic because 'the racial and ethnic categories do not possess equal social standing.' A truly pluralistic society is characterized by its ability to accept and recognize each other's cultural, racial, and ethnic differences and therefore, each cultural category possesses equal social standing. Such a society displays ethical viewpoint and moral relativism. They offer equal respect, competence, and honor for each other. Thus, option C is the correct answer.
