Comprehensive and Detailed Step-by-Step Explanation:
* Reference to IIA Standards:
* Standard 2200 - Engagement Planning: The engagement work program outlines the resources, timelines, and procedures necessary to achieve the engagement's objectives.
* The work program must be approved to ensure alignment with objectives and resource requirements.

* Option B is correct because an approved engagement work program confirms that the scope, procedures, and resources were planned and allocated effectively.
* Option A (staff skills audit) evaluates team competencies but does not confirm specific resource allocation for an engagement.
* Option C (post-engagement survey) evaluates the outcome of the audit but does not provide evidence of initial resource planning.
* Significance of the Work Program:
* The work program ensures that the engagement is structured to meet objectives efficiently, with adequate and relevant resources.

Comprehensive and Detailed Step-by-Step Explanation:
* Reference to IIA Standards:
* Standard 1210 - Proficiency: Internal auditors must possess the knowledge, skills, and competencies needed to perform their responsibilities.

* Option C (assessing development efforts) is a secondary benefit and not the primary goal of providing training.
* Impact of Training:
* A well-trained audit team improves the quality of engagements, ensures adherence to professional standards, and supports the overall effectiveness of the internal audit activity.
