Step-by-step explanation:
The tool that should be used to review changes made to individual components in a company's power platform customizations stored in source control is Power Apps. Power Apps is a low-code platform that allows users to create and customize business apps.
For reviewing changes made to individual components stored in source control, you should use Power Platform's version control capabilities, which is often associated with solutions and environments.
1) **Power Apps:** Power Apps is a low-code application development platform and is not specifically designed for reviewing changes in source control.
2) **Power Automate:** Power Automate is used for automating workflows and is not a tool for reviewing changes in source control.
3) **Power BI:** Power BI is a business analytics tool and is not primarily designed for source control.
4) **Power Virtual Agents:** Power Virtual Agents is a platform for building chatbots, and it does not typically handle source control.
For managing and reviewing changes made to individual components in the Power Platform, you would typically use Power Platform's version control system, which is integrated with solutions and environments. This allows you to track changes, compare versions, and manage the lifecycle of your Power Platform components effectively.
