X is running okay but an administrator is concerned that the correct color depth set is not configured. Which of the following commands will show the administrator the running color depth while in X?

'xcd' is not a standard X utility for displaying color depth; it might be a typo or a non-existent command.

'xcdepth' is not a standard X utility for displaying color depth; it might be a typo or a non-existent command.

The `xwininfo` command, when run without specific window arguments (e.g., `xwininfo -root`), reports detailed information about the root window, which includes the display's visual class and depth (e.g., "Depth: 24"). This directly indicates the current color depth of the X server.

'xcolordepth' is not a standard X utility for displaying color depth; it might be a typo or a non-existent command.

`cat /etc/X11` would display the contents of the `/etc/X11` directory or its configuration files, but it doesn't dynamically show the *running* color depth of an active X session.
