An organization maintains independent departmental risk registers that are not automatically aggregated. Which of the following is the GREATEST concern?

Without aggregation, senior management lacks a consolidated, holistic view of risks across the entire organization, preventing an accurate evaluation of the overall enterprise risk profile, effective prioritization, and informed strategic decision-making regarding risk management.

While inefficient resource allocation can result from fragmented risk information, the inability to accurately assess the overarching risk profile is a more fundamental governance issue that underpins such operational inefficiencies.

Identifying the same risk factor in multiple areas is a symptom of unaggregated data, but the core problem is management's resulting inability to see and address this duplication effectively.

Initiating multiple risk treatment efforts for the same risk is a consequence of lacking a unified view, but the greatest concern is the higher-level inability of management to form an accurate, enterprise-wide risk picture.
