Which of the following is not true of responsibility accounting?

Answer (C) is correct. Responsibility accounting stresses that managers are responsible only for factors under their control. For this purpose, the operations of the business are organized into responsibility centers. Costs are classified as controllable and uncontrollable. This implies that some revenues and costs can be changed through effective management. Management may then focus on deviations for either reinforcement or correction. Thus, the statement that every factor is ultimately controllable by someone is not a premise of responsibility accounting.
