The command that displays all running containers is "docker ps." This command provides a snapshot of the active containers in your Docker environment, listing essential details such as container ID, image name, command, creation time, status, ports, and names. This data allows users to easily monitor and manage their running containers.

"docker ps" has various flags that can modify its output, such as showing all containers, including those that are not currently running (using "docker ps -a"), or filtering the list further based on specific criteria. Its widespread use makes it a fundamental command for anyone working with Docker.

The other command options do not exist within the Docker command-line interface: "docker show," "docker list," and "docker running" are not valid Docker commands for listing running containers. This makes "docker ps" the only correct answer for retrieving a list of currently active containers.
