Safety inspector: The number of laboratory samples of rabies virus sent through the university delivery service has recently grown dangerously high. We need to limit this use of the service. Biologist: There is no need for a limit. The university delivery service has been handling rabies virus samples for 20 years with no accidents. As a rebuttal of the safety inspector's claim, the biologist's reasoning is flawed in that it
A: fails to explain why the number of samples sent through the service has increased
B: offers no defense of the university's need for continued delivery of rabies virus samples
C: overlooks the possibility that there has been a change in the hazardousness of the rabies virus samples themselves
D: does not address the potential for harm that is posed by the recent increase in the number of samples sent through the service
