Final Answer:
In the interpersonal role, managers establish and maintain contacts outside the vertical chain of command through the "Liaison" function. Option D is the answer.
Step-by-step explanation:
The interpersonal role of a manager involves interactions with people both inside and outside the organization. The liaison function specifically pertains to the manager's responsibility to build and maintain relationships beyond the vertical chain of command. Liaisons connect the organization with external entities, such as other organizations, stakeholders, or community groups.
This role is crucial for information exchange, collaboration, and networking. While other interpersonal roles (Figurehead, Leader, Disseminator) focus on internal aspects, the Liaison role emphasizes the manager's external connections, facilitating effective communication and cooperation beyond the immediate organizational hierarchy.
Option D is the answer.
