In Power BI Desktop, which option allows you to modify the data source connection settings?

The option that allows you to modify the data source connection settings in Power BI Desktop is the Data Source Settings. This feature provides users with a centralized location to manage and alter the connections to data sources that have been established. Through Data Source Settings, you can change the credentials, update the path or URL of the source, or even remove connections to data sources that are no longer needed.

This is particularly useful when there are changes in the location of the data, authentication methods, or when using different data sources at varying stages of development. In contrast, Edit Queries, Manage Parameters, and Transform Data serve different functions. Edit Queries lets you perform transformations and data shaping, Manage Parameters allows you to work with different configurations and inputs for your queries, and Transform Data opens the Query Editor for specific data transformation tasks. While all these functions are essential in data preparation, when it comes to changing the connection details of the data sources, Data Source Settings is the specific tool designed for that purpose.
