Which of the following is NOT classified as an excluded injury?

The answer indicating that injuries resulting from work-related duties are not classified as excluded injuries is correct because these injuries fall within the scope of workers' compensation laws. Typically, workers' compensation covers any injury that occurs in the course of employment, as long as it arises out of work-related activities. This means that if an employee is injured while performing their job, such injuries would typically be compensable and not excluded.

In contrast, intentionally self-inflicted injuries and suicides are excluded because they do not arise from the obligations of employment in a manner that workers' compensation is designed to cover. Similarly, psychiatric injuries claimed after notice of termination are also excluded under the law because they often relate to employment status changes rather than ongoing job duties. Thus, option C reflects the principle that work-related injuries are generally compensable under workers' compensation statutes, reinforcing the understanding of what is included versus excluded in such contexts.
