Answer is Right!
Answer is Wrong!
The correct answer is E. None of the above.
A file created yesterday is not called any of the options given. It is simply called “yesterday’s file” or “the file created yesterday”.
The options given are all names that could be given to a file that is created today. A “son” file could be a file that is created by a parent file, a “father” file could be a file that is created by a child file, a “mother” file could be a file that is created by a sibling file, and a “grandfather” file could be a file that is created by a grandparent file.
However, a file created yesterday is not related to any other files in this way. It is simply a file that was created yesterday.
