Which of the following best describes discrimination?

Discrimination is best described as unjust treatment based on various characteristics. This definition encapsulates the essence of discrimination, highlighting how individuals or groups can be treated unfairly due to attributes such as race, gender, age, religion, or disability. The key aspect of discrimination is the inconsistency in treatment that results in a disadvantage or harm to certain people compared to others.

In contrast, the other descriptions do not accurately reflect the concept of discrimination. Understanding diversity and promoting positive outreach are important actions that foster inclusivity and acceptance, but they do not define discrimination itself. A fair assessment of equality implies equitable treatment and judgment of individuals, which opposes the notion of discrimination.
