What is one recognized limitation of internal controls?

Human error is indeed a recognized limitation of internal controls because these systems are designed and implemented by people. Despite the sophistication of internal controls, they are ultimately reliant on individuals to operate them correctly. Mistakes can occur during data entry, processing, or adherence to established procedures, potentially leading to financial inaccuracies or fraud escaping detection. This limitation highlights the importance of continuous training and monitoring to help minimize errors and enhance the overall reliability of the internal control system.

The other options, while they may relate to internal controls, don't capture the inherent challenges linked with human involvement in the process. For example, consistent effectiveness may be desired but is not guaranteed, and strict regulatory compliance is a goal of internal controls rather than a limitation. High initial costs could be a consideration when establishing these controls, but they do not directly speak to the limitations faced in their actual functioning.
