You download multiple container images from Docker Hub and create containers using the docker run command. After a few days, you notice that the list of containers that you have run is quite large. Which of the following commands can you use to shorten this list?

Question

The docker container prune command removes all stopped containers, thereby shortening the list. Option A (docker rmi image) removes an image, not a container; Option B (docker stop container) stops a running container but does not remove it from the list, and Option C (docker rm container) removes a stopped container, but you need to specify the container name or ID, which can be cumbersome for a long list of containers. Therefore, Option D (docker container prune) is the best choice for shortening the list of containers.
