Which option best characterizes the argument for why concerns about job performance are insufficient to justify drug testing in the workplace?$$

Drug testing involves a significant invasion of privacy, and concerns about job performance also involve privacy concerns for the employee. Since employees are not required to disclose private aspects of their lives to their employees, drug testing in the workplace is not morally justified.$$

Drug use does not always negatively impact job performance, so drug testing in the workplace is not justified due to concerns about job performance.$$

Drug testing is only morally justified when it concerns the safety of third parties and not when it concerns job perfomance.$$

Even if drug use impacts job performance, employees are not required to do their best in their jobs$--$they are only required to meet the bare minimum standards of the job. However, if employees are unable to meet these bare minimum standards, then it is this failure to meet a minimum standard that is problematic and$$not$$the drug use that is problematic.$$
