Running the command rm Downloads leads to the following error: rm: cannot remove `Downloads/': Is a directory Which of the following commands can be used instead to remove Downloads, assuming…

'undir' is not a valid Linux command and does not exist in any standard Linux distribution.

The 'rmdir' command is specifically designed to remove empty directories, making it a valid choice when the Downloads directory contains no files or subdirectories.

'dir' with a removal flag is not a valid Linux command for deleting directories.

'rem' is not a valid Linux shell command - it is associated with Windows batch scripting and has no equivalent function on Linux.

The 'rm -r' command enables recursive deletion, which allows rm to remove a directory and all its contents - and also works correctly on empty directories.
