Answer: D - Leniency Error
Explanation: Leniency Error is a subjective appraisal by an employer. This error is based on the employers perception of the employee.
Leniency error gives the employee a perception that he/ she needs no improvement at work due to the high rating from his employer which is not a general appraisal.
The employer only appraises the employee on an aspect of work while other aspect are left. This makes the employee loose focus on areas of improvement and focus more on his high appraisal.
