Which of the following contributes to the reliability of information collected for an audit engagement?

Comprehensive and Detailed Explanation:

Per IIA Standard 2310 – Identifying Information, audit evidence must be sufficient, reliable, relevant, and useful. Reliability depends on the source and control environment. Information obtained from a system with effective controls (A) is more reliable, since the system processes and safeguards ensure accuracy and integrity. A written statement from a manager (B) may be relevant but is subjective. Consistency with objectives (C) and usefulness to organizational goals (D) reflect relevance and utility, not reliability. Therefore, the strongest factor contributing to reliability is that data comes from a system with strong internal controls (A).
