Final answer:
The compensable factor out of the options provided is Skills, as it directly impacts an employee's ability to perform a job and typically influences compensation.
Step-by-step explanation:
A compensable factor is a characteristic of a job that is used to determine pay and includes things like the level of responsibility, skills required, working conditions, and effort needed. Skills required for a position are typically considered a compensable factor since they directly relate to an employee's ability to perform a job. Other options such as benefits, seniority, and exempt status are related to employment terms or classification and are not generally considered direct factors in setting compensation levels.
