Answer:
D. Excludes retirees who are interested in seeking new employment opportunities
Explanation:
Internal recruitment is the process by which an organization fills a job vacancy by hiring someone from the existing workforce. It is a cheaper method, the firm is familiar with the employee, thus less risk and the employee is also familiar with the firm, hence no induction training required.
Since only those who are already working are the only ones who would be eligible under internal recruitment, retirees will not be a part of the pool of potential workers, even if they may be possessing better skills and experience.
