D. LibreOffice, like most word processors, uses a binary format that can't be properly parsed using an ASCII or Unicode text editor. Thus nano won't be useful in examining such a document, making option D correct. The nano text editor can handle ASCII or Unicode format, so the text files described in options A and C are incorrect. The other document types described in options B and E are all likely or certain to be stored in ASCII or Unicode format, making them incorrect choices.
For which type of file is nano least likely to be useful for examining or editing?
A) A text file encoded in Unicode
B) A shell script file
C) A text file encoded in ASCII
D) A LibreOffice word processing document
E) A Linux configuration file
