The electrician charging Hispanic customers more than white customers for the same service is most clearly engaging in discrimination (option c). Discrimination refers to the unfair or unequal treatment of individuals or groups based on certain characteristics such as race, ethnicity, or nationality. In this scenario, the electrician is displaying discriminatory behavior by charging different prices based on the ethnicity of the customers, which is a form of unjust treatment and a violation of equal treatment principles. Stereotyping (option a) refers to making generalizations or assumptions about individuals based on their perceived characteristics, while scapegoating (option b) refers to blaming a particular group for problems or issues. Social scripts (option d) refer to learned patterns of behavior and interaction in specific social situations and are not directly applicable to this scenario.
