A is incorrect: Editing managed components in production by creating unmanaged customization layers violates ALM governance principles. It introduces ungoverned layers, creates solution dependencies that prevent clean uninstallation, and makes future pipeline deployments unpredictable and difficult to manage.

B is correct: Power Platform pipelines automatically store both managed and unmanaged solution artifacts in the pipelines host for every deployment. Makers can initiate a redeployment from a successful deployment record via the Run history tab, enabling a targeted rollback to a known-good version without impacting other solutions.

C is incorrect: Deleting a managed solution removes all custom tables and custom column data associated with that solution, causing permanent data loss. Circumventing the pipeline for reimport also bypasses governance controls, preflight validation, and audit trail capabilities that pipelines provide.

D is incorrect: While environment point-in-time restore is available, it is not a targeted rollback approach. It reverts the entire environment including all solutions, data changes, and configurations made since the backup point, potentially causing broader unintended data loss beyond the affected solution.
