Reasonable assurance, as it pertains to internal control, means that:
a. The objectives of internal control vary depending on the method of data processing used.
b. A well-designed system of internal controls will prevent or detect all errors and fraud.
c. Inherent limitations of internal control preclude a system of internal control from providing absolute assurance that objectives will be achieved.
d. Management cannot override controls, and employees cannot circumvent controls through collusion.
