The native RTR command for deleting a file or directory is rm. To remove a non-empty directory, the operation must be recursive, represented by r, and force removal is represented by f. Combining those switches produces rm followed by the quoted directory path and -rf. Quoting the Windows path ensures that the complete path is handled as one argument, which is especially important when paths contain spaces. The remove command shown in options A and D is not the native RTR command name for this operation, and - force is not the syntax presented by the choices. Because the task explicitly requires deleting the folder and everything beneath it, rm " C:\Windows\BadTools " -rf is the only option combining the correct command with recursive forced removal.
