How can you remove a Docker image?

The command used to remove a Docker image is "docker rmi [image_id]". This command specifically targets Docker images and is designed to delete them from the local repository. When you execute this command, Docker will attempt to remove the specified image, and if there are no dependent containers, it will succeed.

The reason for using "docker rmi" is that it directly indicates the removal of a repository and image name. This command is part of Docker's core commands for managing images and is universally recognized within the Docker CLI (Command Line Interface).

The other options mentioned do not perform this function. For instance, "docker delete" is not a valid command in Docker, and "docker rm" is specifically for removing containers, not images. Additionally, while "docker image remove [image_id]" might seem like a plausible command, it is actually not the correct syntax recognized by Docker as of the latest standards. Only "docker rmi" accurately serves the purpose of removing images.
