Which option should you use to automatically remove a container after it exits?

• A. -rm
• B. --rm
• C. -remove
• D. -delete

Answer: (B)

Automatically removing a container after it exits is controlled by the --rm flag on the run command. When you run a container with this option, Docker will automatically delete the container as soon as the main process finishes, which helps keep your environment clean without leaving stopped containers behind. This flag only affects the container instance itself; the image remains on your system for future runs. Data inside mounted volumes can persist depending on how you configured them, so be aware if you rely on volumes for persistence. The other strings listed aren’t valid options for this purpose, so they won’t trigger automatic removal.
