The correct answer is Power BI.

Power BI is designed specifically for creating scalable interactive dashboards and for exploring and visualizing business datasets. It offers rich visualizations, drag and drop report authoring, real time dashboards, and enterprise scale options such as Power BI Premium and embedding so organizations can serve many users and handle large datasets.

Azure Synapse Analytics is an integrated analytics platform for large scale data warehousing and big data processing and it focuses on data integration and complex analytical queries rather than end user interactive dashboarding. It can supply data to visualization tools but it is not the primary reporting service.

Azure Data Factory is a data integration and ETL service for moving and transforming data across systems and it is not intended for building interactive dashboards or visual reports.

Azure Machine Learning is focused on training, deploying, and managing machine learning models and model operationalization and it does not provide the core dashboarding and business visualization features that Power BI offers.
