The best course of action when the internal audit activity lacks the necessary knowledge for a planned audit is to Provide data backup training to the engagement supervisor. This option ensures that the audit team builds the required competencies internally, enhancing their ability to perform the audit effectively.

Option B: Recruiting a full-time staff auditor is not a practical immediate solution and could be resource-intensive.

Option C: Changing to a consulting engagement does not solve the knowledge gap for future audits.

Providing training aligns with the IIA Standard 1210.A1, which requires internal auditors to possess the knowledge, skills, and other competencies needed to perform their responsibilities.

IIA Standard 1210: Proficiency and Due Professional Care.

IIA Standard 1230: Continuing Professional Development.
