Which of the following is a Power BI feature that supports report sharing?

The Power BI Service is the correct choice for supporting report sharing because it is the online platform designed specifically for collaboration, sharing, and managing Power BI reports and dashboards. Users can publish their reports created in Power BI Desktop to the Power BI Service, making them accessible to others within their organization or with external users, depending on permissions set. This cloud-based solution facilitates real-time sharing and allows for interactive visualizations that can be worked on collectively.

Other options, like Power BI Desktop, while essential for creating reports and visualizations, do not inherently support sharing features as they operate as a local application. The Power BI Query Editor focuses on data transformation and preparation but does not cater to sharing functionalities. Power BI Report Builder is designed for paginated reports, which are a different type of reporting that may require separate handling when it comes to sharing. Hence, the Power BI Service is specifically tailored for sharing reports and collaborating within teams or organizations.
