What command should be entered to print and then delete the file, foobar.txt?

The `-0` option is not typically used for file removal, and `delete` is not a valid option to remove the file after printing with `lpr`.

The `-d` option in `lpr` usually specifies the destination printer or class, not to delete the source file.

The `lpr -r foobar.txt` command sends `foobar.txt` to the print spooler and then automatically removes (deletes) the original file after it has been successfully spooled for printing.

The `-0` option is not used for file removal, and `remove` is not a recognized `lpr` option for this purpose.
