When selecting a UIC hierarchy, if the results are greater than 1,000 then an error message displays indicating a lower level UIC must be selected. This statement is:

The statement is accurate because it outlines a fundamental aspect of UIC (Uniform Identification Code) hierarchy management. In systems that utilize UICs, there is a specific structure intended to maintain organized data entry and retrieval. When results exceed 1,000, it often indicates that the current selection is too broad or lacks specificity. Therefore, the system prompts users to select a more granular, lower-level UIC to refine the search results. This requirement helps ensure that the data remains manageable and relevant, adhering to the system's design principles.

Understanding this dynamic is crucial for effective data management, as it enhances user experience by guiding users towards more precise queries and correct usage of the hierarchical structure. Other choices do not align with the established rules of UIC selection, making them less relevant in this context.
