B) Is more difficult to evaluate because the supervisor and the employee could have different skills

D) ​None of the above

In a firm organized along functional lines, supervisors and employees typically have similar skills because they work within the same functional area (e.g., marketing, finance, operations). This similarity in skills can make it easier to evaluate employee performance, as the supervisor is likely to have a good understanding of the tasks and challenges faced by the employee.
