Quizplus · Accepted Answer

Choice C represents an internal validity threat because it suggests that both drug use and crime can be attributed to other causes, which means that it is difficult to establish a cause-and-effect relationship between the two variables. Choices A and B do not represent internal validity threats as they are related to external validity (generalizability) and the scope of the relationship, respectively.
