Which feature allows you to flag custom objects for changes within a Scratch Org?

The feature that allows you to flag custom objects for changes within a Scratch Org is focused on managing your code and asset changes effectively. When using version control systems alongside Salesforce DX, the "Commit Changes" functionality enables developers to mark specific changes in the Scratch Org for inclusion in a version-controlled repository. This is essential for tracking modifications to custom objects or any other metadata components and allows for structured collaboration among team members.

This method streamlines the process of maintaining consistency in data and object definitions across development environments, ensuring that what is modified in the Scratch Org can be accurately pushed or merged into a shared repository. By committing these changes, developers can review what has been altered, document those changes, and ensure that only the required modifications are captured before deploying to production or integrating further.

The other choices relate to processes or functionalities that do not specifically allow for flagging changes to custom objects explicitly. For instance, "Scratch Org Operations" pertain to the management and usage of the Scratch Org itself, while "Package Deployment" deals with the distribution of packaged updates rather than flagging changes. "DX Panel Validation" typically involves ensuring compliance with Salesforce best practices or guidelines but does not perform the act of marking or committing specific changes.
