The correct answer is: A. individuals.
Human relations theory is a theory of management that emphasizes the importance of interpersonal relationships and communication in the workplace. It is based on the idea that employees are more productive when they feel valued and respected, and when they have a sense of belonging to a team.
Human relations theory focuses on the individual employee, and how their needs and motivations can be met in the workplace. It emphasizes the importance of communication, cooperation, and teamwork. Human relations theory also emphasizes the importance of the informal organization, which is the network of relationships that exists among employees outside of the formal organizational structure.
The other options are incorrect because they do not focus on the individual employee. Option B, "role of individuals," is too broad. Option C, "system," refers to the overall organization, not the individual employee. Option D, "informal organization," is a subset of the organization, not the individual employee.
