Which command is used to remove a Docker container?

• A. docker prune
• B. docker rm
• C. docker rmi
• D. docker stop

Answer: (B)

Removing a Docker container is done with the remove operation on containers. The command docker rm deletes container objects from the host, which is exactly what you want when you no longer need the container. A container must be stopped before removal; if it's still running, the command will fail unless you force it with -f, which stops and removes in one step. The other options don’t remove containers: docker prune (or system prune) cleans up unused data, not a specific container. docker rmi removes images, not containers. docker stop just halts a running container but doesn’t remove it.
