Why each option

The `docker info` command provides a comprehensive overview of the Docker daemon's configuration and environment on the host system.

Adocker infoCorrect

The `docker info` command displays detailed system-wide information about the Docker daemon, its environment, operating system, kernel, storage driver, plugin status, and various other configurations, making it ideal for checking the overall Docker setup.

Bdocker status

`docker status` is not a standard Docker CLI command for displaying system-wide configuration.

Cdocker inspect

`docker inspect` is used to retrieve low-level information about a specific Docker object (e.g., a container, image, or network), not the entire system-wide configuration.

Ddocker system

`docker system` is a subcommand group (e.g., `docker system prune`), but the command `docker system` alone does not display system-wide Docker configuration.
