Danielle, the owner of an apartment , wants to rent out one of the rooms. She disregarded the application of Rita, an Asian woman, because Danielle wanted to rent her apartment only to whites. In this scenario, Danielle's action is an example of .

Individual discrimination.

Explanation:

Individual discrimination generally means "discrimination against another individual".  Individual discrimination occurs when a person is unfairly treated by another based on their race, class, colour, and gender. It also deals with restricting another person from doing or getting something based on how that person is perceived. For instance, an employer may prefer to hire a white worker for a specific position and refuse any black applicant or a real estate manager refusing to sell a house to an Asian couple and so on.

Given the above, Danielle's action in refusing to rent the apartment to the Asian woman clearly indicates "individual discrimination".
