Which option allows you to view all the available Docker command parameters?

• A. docker --help
• B. docker --version
• C. docker help
• D. docker info

Answer: (A)

Viewing the CLI help output shows all the available Docker command parameters. Running the main Docker command with the --help flag prints usage information, including the global options and the available subcommands, giving you the complete list of flags and how to use them. In contrast, asking for the version shows only the version information, and while docker help can be similar to --help in some versions, it isn’t guaranteed to consistently display the full set of options. docker info, on the other hand, provides details about the Docker daemon and environment, not the command-line options. So, using the main command with --help is the standard way to view all parameters.
