Prejudices are often grounded in:-

Stereotypes

The correct answer is Option (3) → Stereotypes

Prejudices are preconceived opinions or attitudes that are not based on actual experience or objective reasoning. They are often grounded in stereotypes, which are oversimplified and generalized beliefs about a group of people. These stereotypes shape perceptions and judgments before any direct interaction or evidence is considered, leading to biased behavior and discrimination.
