What command would you run to check the number of Docker containers and images?

Using the command "docker info" provides comprehensive information about the Docker installation on your system, including key statistics related to containers and images. Specifically, it lists the total number of containers, along with how many are currently running versus stopped, as well as the total number of images that are available locally on your Docker host.

This command is particularly useful for system administrators and developers to quickly assess the state of their Docker environment without running multiple commands. In contrast, the other options do not return this specific summary effectively, which is why they do not serve the intended purpose of checking the count of Docker containers and images.
