Selection as a tool of personnel management refers to:

Selection is a crucial stage in the personnel management process, following recruitment. Its primary objective is to identify and choose the most suitable candidate from a pool of applicants who have responded to a job vacancy. This involves evaluating candidates' qualifications, skills, experience, and cultural fit against the specific requirements of the job and the organization. The goal is to ensure that the individual hired possesses the best potential for successful job performance and long-term retention. Therefore, A: Choosing the most suitable candidate from a pool of applicants is the correct definition. B: Advertising a job vacancy is part of recruitment, which precedes selection. C: Training new employees occurs after selection and onboarding. D: Conducting exit interviews happens when an employee leaves, providing feedback, and is unrelated to the selection process itself.
