What are the key components of a Power BI workspace?

The key components of a Power BI workspace include datasets, reports, dashboards, workbooks, and dataflows.

Datasets are collections of data that are used to create reports and dashboards. They can be created by importing data from various sources or through connections to live data. Reports are the visual representations of the data that provide insights through charts, tables, and other visuals. Dashboards serve as a single-page, interactive view of the most critical metrics and KPIs, allowing users to monitor their data at a glance. Workbooks can refer to Power BI reports created in Excel or Power BI Desktop that can be published to the workspace. Dataflows allow for the ETL (Extract, Transform, Load) process to be managed within Power BI, enabling data preparation and transformation.

This comprehensive structure allows users to effectively manage and utilize their data, making option B the most accurate representation of the components within a Power BI workspace. Other responses either mix components that don't fit the context of a workspace or focus on too narrow or unrelated aspects of Power BI functionality.
