There is no answer for this, because it is the wrong question. A files extension doesn't matter to the file, it only exists so that the Operating System (OS) knows what application to open the file with. Technically you can have a text file with no extension if you don't mind telling Windows what program to use to open the file every time.
Generally speaking .txt is the most common choice though.
The file is just a plain text file. Txt is an abbreviation for text.

The file extension tells about the type of file, with the extension three letters. For Eg:- *.txt -- text file *.exe-- executable file
It is a plain text file, just text, no graphics, no formatting, no colours or anything like that. It is just for when the text is important, not how it looks. Web pages and programs and data are often in plain text files. Applications like Notepad are used to create text files.
