When the CAE determines whether the internal audit activity has confirmed the status of all management's corrective actions, it helps in assessing residual risk. Residual risk is the risk that remains after management's actions to mitigate inherent risk. By confirming the status of corrective actions, the CAE can evaluate whether the risks identified during the audit have been adequately addressed and what level of risk still exists, ensuring that the internal control environment is effective and that management's risk responses are appropriate.

According to Standard 2440 - Disseminating Results, internal auditors should communicate significant observations timely, especially high-risk issues that require immediate attention. Verbal communication upon identification allows management to act quickly, while formal documentation ensures proper recording and follow-up. Option B reflects this balance by providing both verbal escalation for high risk and documented evidence of findings with root cause, effect, and recommendation.

According to IIA guidance, before implementing any changes to the audit program's scope prior to beginning fieldwork, the most important action is to seek approval from the chief audit executive (CAE) for the proposed scope change. This ensures that any significant modifications are reviewed and authorized at the appropriate level, maintaining the integrity and alignment of the audit activity with the organization's audit plan and objectives.

Promoting objectivity in internal auditing involves ensuring that auditors avoid conflicts of interest and maintain independence in both fact and appearance. Policies that clearly define and give examples of inappropriate business relationships help auditors understand and avoid situations that could impair their objectivity.
IIA Standard 1120 (Individual Objectivity) emphasizes the importance of internal auditors maintaining an unbiased mindset and avoiding conflicts of interest.

Generalized audit software (GAS) is specifically designed to assist auditors in performing various audit tasks, including extracting specific files and records from databases. GAS tools, such as ACL and IDEA, allow auditors to import data from various systems, query databases, perform data analysis, and generate reports.
This makes them ideal for tasks that require the extraction and examination of specific records or data sets within a database. Other options, such as expert systems or system utility programs, do not offer the same targeted capabilities for data extraction relevant to auditing tasks.
