The correct option is Load data into Power BI Desktop, design reports, publish to the Power BI service and then view and interact in the service and mobile.

This answer is correct because Power BI Desktop is the primary authoring environment where you import, shape, and model data and create visuals. After authoring you publish the report to the Power BI service to enable sharing, scheduled refresh, and collaboration, and then users view and interact with the published report in the service or on mobile devices.

Create a report in the Power BI service then send it to the Power BI mobile app and open it in Power BI Desktop is incorrect because the typical flow is to author in Power BI Desktop rather than author in the service and then reopen in Desktop. The mobile app is intended for viewing and interacting and not for authoring or transferring reports back to Desktop.

Import data into Power BI mobile, build the report there and then export it to Power BI Desktop is incorrect because the Power BI mobile apps do not support full data import and report authoring or exporting to Desktop. Mobile apps are designed for consuming published content.

Author paginated reports in Power BI Report Builder then publish them and try to edit the original dataset in Power BI Desktop is incorrect because paginated reports are a separate scenario created with Report Builder for pixel perfect output. You do not usually publish a paginated report and then edit its dataset in Desktop as datasets are often managed in the service or created in Desktop first.
