Which of the following is an example of discrimination?

Discrimination refers to the unfair treatment of individuals based on characteristics such as race, gender, age, or other attributes rather than their qualifications or abilities. The scenario of choosing not to hire someone based on their race is a clear example of discrimination because it involves making a hiring decision that is directly influenced by the individual's racial background, rather than their skills or suitability for the position.

In contrast, promoting equality in the workplace, encouraging diversity among employees, and creating fair policies for all employees are all actions aimed at fostering an inclusive environment. These actions seek to eliminate discrimination and ensure that all individuals have equal opportunities, regardless of their race or background. Thus, they do not exemplify discrimination, but rather serve to combat it.
