Answer:
C. Able but unwilling
Step-by-step explanation:
Close supervision of an employee is most required when the employee is unable but willing to perform their tasks. In this case, the employee may have the desire to complete the task, but they lack the necessary skills or knowledge to perform it correctly, which can lead to errors and mistakes. Close supervision in this situation can help ensure that the employee receives proper guidance and support to learn how to complete the task correctly, which can lead to increased productivity and better performance.
