Which of the following is an example of racial bias?

The correct answer is an example of racial bias because it specifically refers to prejudice that is directed at individuals based on the color of their skin. Racial bias encapsulates any negative attitudes or actions towards a person solely because of their race or ethnicity, and skin color is a visible characteristic that often determines how individuals are perceived and treated in society. This form of bias can manifest in various aspects, including social interactions, employment opportunities, law enforcement practices, and education.

Other options represent different forms of discrimination or bias that, while harmful, do not fall under the category of racial bias. Discrimination based on beliefs or ethnicity and bias against sexual orientation are distinct in that they pertain to different facets of identity, such as religion or sexual identity, rather than race or skin color specifically.
