Final answer:
An auditor's responsibility to detect client noncompliance with laws may vary depending on whether the law has a direct or indirect effect on the financial statements.
Step-by-step explanation:
In the identification of client noncompliance with laws, an auditor's responsibility may vary depending on the nature of the laws. Generally, an auditor is responsible for detecting noncompliance with laws that have a direct effect on the financial statements. This means that if a law directly impacts the financial statements, the auditor has a responsibility to detect any noncompliance.
On the other hand, if a law has an indirect effect on the financial statements, the auditor's responsibility may differ. However, the auditor still has a duty to perform procedures to assess the risk of noncompliance and obtain sufficient evidence to ensure that the financial statements are not materially misstated due to noncompliance with such laws.
Therefore, statement (a) is correct: an auditor's responsibility to detect noncompliance differs depending on whether the law has a direct or indirect effect on the financial statements.
