Span of control refers to the maximum number of subordinates that a manager may manage effectively. When a manager has a small number of subordinates under him, he can efficiently govern them.

Hence, the correct option is D. "the span of control".

The quality of work done in any organization is directly proportional to the number of direct reports or the span of control. As a result, a wide range of control is required to ensure that all of the company's tasks are completed successfully and efficiently.

The correct answer is letter "D": the span of control.

Explanation:

The span of control is the number of personnel subordinated that must be assigned to every managerial position. A variation with this number has a direct effect on the increase or decrease of hierarchical levels. A narrow span of control results in hierarchical organizations while a wide span of control results in a flattened structure. The size of a company is determined for the span of control of its employees, its reach of its operations, and its importance in the market.
