To create a new Docker container from an image, the appropriate command is 'docker run'. This command not only creates a new container from the specified image but also starts it immediately. It allows you to specify various options such as ports, environment variables, and volume mounts directly at the time of creation.

Using 'docker build' is meant for building images from a Dockerfile, which is fundamentally different from creating and running a container from an existing image. Likewise, 'docker image create' does not exist as a command; you typically use 'docker pull' to download images or 'docker build' to create them. The command 'docker create from image' does not follow the correct syntax for Docker commands and is not valid. Thus, the 'docker run' command is the only one that correctly describes the process of creating and starting a container from an image.
