C

Explanation:
The correct answer is C, Prepared frequently. Operational managers, such as supervisors and front-line managers, require information to organize and monitor daily operational activities. This information must be prepared frequently to support real-time or near-real-time decision-making for routine tasks. Information in summary form (A) is more typical for higher-level management, information about the organization as a whole (B) is relevant to strategic management, and information relevant to the long-term (D) is used for strategic planning, not daily operations. Frequent preparation ensures operational managers have timely data for effective management of daily activities.
