Which of the following is NOT a common type of audit engagement?

Market analysis is not a common type of audit engagement because it primarily focuses on assessing market conditions, trends, and competitive environments rather than evaluating an organization's financial statements, compliance with laws and regulations, or the effectiveness of internal controls.

Audit engagements typically concentrate on providing assurance on the accuracy and reliability of financial reporting (financial statement audits), evaluating the adequacy and performance of an organization's internal control system (internal controls audits), and ensuring compliance with relevant laws, regulations, and internal policies (compliance audits). Market analysis, while an important business assessment tool, does not fall under the traditional categories of audit engagements that are concerned with verifying, validating, and ensuring adherence to financial and operational standards.
