Prejudice is defined as

• A. Unfair or unequal treatment
• B. Judgement of people in terms of stereotypes or generalizations
• C. Official policy
• D. A lack of knowledge

Answer: (B)

Prejudice is forming judgments about people based on stereotypes or generalizations about the group they belong to, before you know them personally. It’s an attitude or belief about a group, often negative, that leads you to pre-judge individuals. That’s why this option fits best: it directly captures judging people by broad generalizations about their group. The other ideas describe outcomes or conditions rather than an attitude: unfair or unequal treatment is discrimination, official policy is rules set by institutions, and a lack of knowledge is ignorance.
