Final answer:
Auditors use the most rigorous audit procedures for examining management assertions that are high risk to ensure financial statements are accurate and to mitigate the risk of fraud.
Step-by-step explanation:
Auditors are most likely to use the most rigorous audit procedures to examine management assertions that are deemed to be of high risk. Audit procedures vary depending on the risk assessment of the assertions made by management in their financial statements. High-risk areas receive more attention to ensure that the financial statements are free from material misstatement. This approach is consistent with the risk-based auditing standards that encourage auditors to focus on areas where there is a higher risk of error or fraud.
