correct option is a.
Step-by-step explanation:
An organization comprised of many levels with narrow spans of managerial control is described as flat. In a flat organizational structure, there are fewer layers of management and a wider span of control, which means that each manager supervises a larger number of employees. This allows for quicker decision-making and increased communication within the organization. On the other hand, a tall organizational structure has many levels of management with narrow spans of control, resulting in a longer chain of command and more potential for communication delays.
