Selected Answer: B
The complete process to fully delete an image from DTR requires additional steps: Delete the image through the DTR interface or API Delete the repository Run garbage collection The garbage collection step is crucial because: * When you delete images/repositories from DTR, the actual image files remain on disk * These files are marked for deletion but are not immediately removed * Only after running garbage collection will the actual disk space be reclaimed * This is a safety mechanism to prevent accidental data loss
