A user removed the Docker containers on the system. He now wishes to have all of the stopped containers removed.Which of the following commands can he use?docker rm $(docker ps -aq)docker remove $(docker ps -a)docker rm $(docker ps -a)docker remove $(docker ps -aq)

The correct command to remove all stopped Docker containers is:

docker rm $(docker ps -aq)

Here's the step-by-step explanation:

1. docker ps -aq: This command lists all containers (both running and stopped) in quiet mode (-q), which only displays their numeric IDs.

2. $(docker ps -aq): The $() syntax in bash is used to denote command substitution, meaning it replaces the command with its output. So,$(docker ps -aq) will be replaced by the IDs of all containers.

3. docker rm: This command is used to remove one or more containers. When combined with the previous command, it will remove all containers that are currently not running.

The other commands listed are incorrect because "docker remove" is not a valid Docker command. The correct command to remove Docker containers is "docker rm".
