I recommend you to consult the relevant manual:
https://www.gnu.org/software/auctex/manual/auctex/Multifile.html

,----
| If you insert

| 
|      (setq-default TeX-master nil) ; Query for master file.
| 
|    In this case, AUCTeX will ask for the name of the master file
| associated with the buffer.  To avoid asking you again, AUCTeX will
| automatically insert the name of the master file as a file variable
`----
,----
|  -- Command: TeX-master-file-ask
|      ('C-c _') Query for the name of a master file and add the
|      respective File Variables (*note (emacs)File Variables::) to the
|      file for setting this variable permanently.
| 
|      AUCTeX will not ask for a master file when it encounters existing
|      files.  This function shall give you the possibility to insert the
|      variable manually.

N.B. The web manual falls behind the recent revise of the document and
contains obsolete sentence "If AUCTeX finds the line indicating the end
of the header in a master file (TeX-header-end), it can figure out for
itself that this is a master file.", which isn't true.

More precisely, that occurs when TeX-master is customized to nil, as
described above.

That's TeX-master-file-ask, bound to C-c _ and available in menu item
LaTeX->Multifile/Parsing ->Set Master File also.
