The scenario highlights that byproducts (normally waste) have market value and can also be purchased by employees at negligible cost. This creates a perverse incentive for production staff to increase production losses intentionally, since greater loss produces more byproducts available for resale or employee benefit.
This risk directly affects internal controls and fraud risk assessment.
Options B, C, and D are not supported by the scenario. The most relevant engagement risk is Option A.

* Diversion typically involves redirecting resources or assets for personal use, not just having an undisclosed interest.

According to the Institute of Internal Auditors (IIA) guidance, organizations have the most influence over the
"opportunity" aspect of the fraud triangle. The fraud triangle consists of three elements: pressure, opportunity, and rationalization. While pressure and rationalization are largely influenced by personal and external factors beyond the organization's direct control, opportunity refers to the circumstances that allow fraud to occur, which can be directly managed and controlled by the organization through internal controls, policies, and procedures.
