Which statement is true about map views, map frames, and map layouts in ArcGIS Pro?

The statement that the map layout contains one or more map frames, each of which contains a map view, is accurate because it accurately depicts the hierarchical relationship among map components in ArcGIS Pro. A map layout serves as the layout space where various elements are arranged for final output, such as a printed map. Within this layout, map frames act as containers that hold the map views, which represent the actual maps displaying spatial data. This structural arrangement allows users to manage and present multiple map views within a single layout effectively.

In this context, it's also important to understand the characteristics of the other concepts mentioned. The map view provides an interactive window showing spatial data and can differ from what's printed, as it is primarily designed for viewing and editing data dynamically. While a map frame contains a map view, the frame itself does not incorporate layouts directly; it is rather a component within the layout. Furthermore, the statement suggesting there’s no difference between these terms oversimplifies their roles, which are distinct and serve specific purposes in the map-making process within ArcGIS Pro.
