Answer:
B. a staff manager
Step-by-step explanation:
A staff manager is in charge of a revenue consuming department in an organization. He or she is in charge and supervises the employee in that department. Examples of revenue consuming departments include accounting, human resources, and customer service. The main role of staff managers is to keep employees motivated, well-informed, engaged, and focused.
Staff managers form an important link between employees and top management. Even though they don't make operating decisions, they help in the decision-making process by providing information and guidance. Unlike the line managers, the staff managers do not have directs control of employees, neither are they engaged in managing the day to day business operations of the organization.
