B, is the correct answer. The number of accidents that occur. Sure, the supervisor may be able to influence the number of accidents through all the other activities listed, but he or she can not actually control the actual outcome. If supervisors are held accountable for an outcome for which they have no control, they will naturally try to gain control over that outcome somehow: The methods they use to do that may not be ethical or otherwise in the best interests of the employer. Emphasize measurement of activities, not outcomes.
