The correct answer is: B. Informal
Informal appraisal is conducted in small units having only a few personnel. It is a less structured and more informal process than formal appraisal. It is often conducted by the manager or supervisor of the employee, and it may involve feedback from other employees or customers. Informal appraisal can be a valuable tool for providing feedback to employees and helping them to improve their performance.
Formal appraisal is a more structured and formal process that is typically conducted in larger organizations. It is often conducted by a human resources professional, and it may involve feedback from multiple sources, such as the employee’s manager, peers, and subordinates. Formal appraisal can be a valuable tool for assessing employee performance and making decisions about compensation, promotions, and training.
Initial appraisal is the first appraisal that an employee receives. It is typically conducted after the employee has been with the organization for a short period of time, such as six months or one year. Initial appraisal can be a valuable tool for providing feedback to employees and helping them to set goals for their future performance.
None of these is the correct answer because it does not describe a type of appraisal.
