Answer:
A) Wide span of management control and flat organizational height
Step-by-step explanation:
Ivan Boston is a regional sales manager, and that makes him a middle level manager. In a traditional tall organization, he would have one or two layers of lower managers that are responsible for the salespeople throughout the region.
But in this case, he is directly responsible for the salespeople, there are no lower level managers in the middle. This means that the organization is flat with few managerial levels and that Ivan is responsible for a large number of subordinates, i.e. he has a wide span of management control.
