正解:B,D,E
In the Lightning App Builder, the following standard components can be used to enhance the functionality of Lightning pages:
* B. Rich text: Allows the inclusion of formatted text, links, and images on a page.
* D. Report details: Enables embedding of specific report details directly on a page.
* E. Recent items: Displays a list of recently accessed items relevant to the user.
Steps to add these components:
* Open the Lightning App Builder via Setup # Edit Page or when creating a new Lightning page.
* Drag and drop the Rich text, Report details, and Recent items components from the standard components section onto the page layout.
* Configure each component as needed (e.g., selecting a specific report for the Report details component).
