Which three key reasons explain why an effective employee selection process is critical to organizational success? (1) Optimizing job execution and securing employee commitment to tasks. (2) Building a workforce equipped with appropriate skills and capabilities. (3) Managing and mitigating the financial expenses associated with talent acquisition. (4) Mandating union representative participation in daily hiring decisions. Choose the correct option:

An effective selection system impacts organizational performance in three primary ways: Work performance and motivation (1): Selecting candidates who fit the job requirements ensures high job performance and strong willingness to work. Quality of human resources (2): It ensures the organization retains qualified and skilled personnel. Cost efficiency (3): Recruiting and onboarding carry significant monetary costs, so making right-fit hiring decisions minimizes wasteful expenditure. Statement (4) is incorrect because union representative involvement is not a core strategic reason driving the functional effectiveness of the selection process.
