- A. To remove unused resources from the Git repository
- B. To delete resources that are no longer defined in Git from the target cluster
- C. To clean up old application revisions from Argo CD's history
- D. To optimize the application's resource usage

**Answer:** To delete resources that are no longer defined in Git from the target cluster

When enabled, Argo CD will remove resources that exist in the cluster but are not defined in the Git repository.
