What should be included in the application for any dashboards?

The correct answer emphasizes the importance of including the specific fields that appear in the dashboards themselves. When creating or refining an application for dashboards, it is essential to ensure that the relevant data points are directly represented in the dashboards for effective visualization and analysis. This allows users to monitor key metrics and make informed decisions based on the information displayed.

Including fields found in the dashboards ensures that these data points are readily accessible and accurately reflect the metrics that the organization wishes to analyze. By focusing on the actual fields used in the dashboards, users can also streamline the application to enhance performance and usability, giving a clearer view of the business's data insights.

The other options center around broader categories or types of fields. While layouts and system fields can contribute to the overall functionality of the application, they do not provide the targeted focus needed for dashboard development. Numeric fields alone do not capture the complete picture, as dashboards may contain a variety of data types necessary for comprehensive reporting. Therefore, prioritizing dashboard-specific fields guarantees that the application is closely aligned with the visualization goals.
