Characterized by unequal opportunities and rewards for different social classes in a society.

The correct answer is Social Conflict.

Explanation:

Social Conflict is characterized by unequal opportunities and rewards for different social classes in a society.

When there is an inequality in the distribution of resources, power, education, work, etc, then it generates social conflict, and this social conflict affects large number of people in the society.

For example, if education in a renowned institute is offered only to the students who belongs to an upper financial class, then this is considered as a social conflict in which equal opportunity rights are not given to every student of the society.
