The answer is B: Oppression.
Explanation for each option:
a. Discrimination: This refers to the unjust or prejudicial treatment of different categories of people, especially on the grounds of race, age, or sex. While discrimination can be a component of oppression, it does not fully encompass the idea of putting extreme limitations and constraints on a group or institution.
b. Oppression: This is the systematic and pervasive mistreatment and exploitation of a group or institution, often involving the imposition of severe restrictions and limitations. It is characterized by the exercise of authority or power in a burdensome, cruel, or unjust manner.
c. Stereotyping: This involves oversimplified and fixed ideas or images of a particular type of person or thing. Stereotyping can contribute to discrimination and oppression but does not directly refer to the act of imposing extreme limitations and constraints.
d. Human diversity: This term refers to the variety of differences among people, including race, ethnicity, gender, age, sexual orientation, and more. It is a neutral or positive concept that celebrates the range of human differences, rather than imposing limitations or constraints.
