Internal control refers to the processes, procedures, and activities implemented by an organization to ensure that its objectives are achieved effectively and efficiently. Motivated individuals and groups exercising self-discipline in fulfilling job requirements is a key aspect of internal control, as it helps to prevent errors, fraud, and other undesirable outcomes. While the other options may also be important aspects of internal control, they are not as fundamental as self-discipline among employees.
