Final answer:
In the job performance equation P = M × A × E, the variable 'A' (Ability) reflects the quality of the employee's work, as it is related to the skills and competencies they bring to their job tasks.
Step-by-step explanation:
In the job performance equation P = M × A × E, the variable that reflects the quality of the employee's work is A (Ability). 'P' stands for Performance, which is the overall output or result of the employee's work. 'M' represents Motivation, which is the level of drive or enthusiasm the employee has toward their work. 'E' stands for Environment, which refers to the external conditions and factors that can affect the employee's work, such as workplace culture, resources, and management support. Therefore, 'A' is the correct choice since it directly pertains to the employee's skills, competencies, and the overall quality they bring to their job tasks.
