The correct answer is C. Inequality
Step-by-step explanation:
The word "inequality" refers to the existence of differences between groups in a society, this includes differences in income, living conditions as well as differences in the access to opportunities, education, health services, etc. This often implies people in low classes cannot escalate in society due to inequality and this makes poverty and inequality to persist. Additionally, this term differs from "discrimination" because, in discrimination people of a specific gender, origin, religion, etc. are legally or socially treated differently just because of this, which might also lead to inequality. Thus, the term for a society in which one group has different opportunities than other groups is characterized by inequality.
