Correct Answers: B and D 
Power BI has a visual dedicated to the integration between Power BI and Power Apps. This Power Apps visual can add your canvas app to a Power BI dashboard or report. It establishes the live data connection between the app and the report`s data. If data changes in the report, it will update the data in a canvas app as well. 
You can use an existing canvas app or create a new app. The Power Apps visual adds a PowerBIIntegration object to your app that serves as a live link between two Power Platform products. After Power Apps visual adds the integration object, you need to save and publish your canvas app. Then you can share the app with the dashboard`s or report`s users that would have access to your canvas app.
