To remove a Docker image, which command would you use?

The command to remove a Docker image is represented by the option that uses the syntax "docker rmi [image_name]." This command specifically stands for "remove image" and is the standard method for deleting images from a local Docker repository.

When executed, "docker rmi" instructs Docker to look for the specified image by name and remove it, if it is not in use by any running containers. This is a critical function for managing disk space and cleaning up unused images in your Docker environment.

While there are other Docker commands such as "docker image remove" that also serve a similar purpose and exist in Docker's more recent versions, the command "docker rmi" is the most commonly used and widely recognized for this action. The other suggested options either do not follow the proper Docker command structure or are nonexistent commands, which makes them incorrect for removing a Docker image.
