One of the Challenges in the Acceptable Risk Approach to Workplace

One of the challenges in the acceptable risk approach to workplace health and safety is that it:

A) is a liberal approach to workplace health and safety that allows employees to recognize the risk they are likely to face.
B) involves the determination of "relative risks," the calculation of which is a complicated process and not always reliable.
C) assumes an equivalency between workplace risks and other types of risks when there are significant differences between them.
D) It treats health and safety merely as an instrumental value and denies its intrinsic value.
