What does the property "Show multiple elements as" determine?

The property "Show multiple elements as" is focused on how breakdown elements are represented in visualizations and reports. When this property is set, it determines whether the breakdown elements are displayed individually or combined into a single trend. This is particularly useful in analytics because it allows users to analyze trends in a more straightforward way, especially when dealing with multiple data sets or segments.

By choosing to show these elements as combined, users can gain insights into overall behavior or trends without getting lost in the details of each individual element. On the other hand, displaying them separately would enable a granular analysis, providing a clear picture of how each individual element contributes to the overall trend. Hence, option C accurately captures the purpose of this property in the context of data visualization and analysis, allowing for flexibility in how data is presented based on the needs of the analysis.
