(b) The writ and process in a quo warranto proceeding shall be served on the defendant personally.

(c) Service of the writ and process in such proceeding upon a resident of this state who is temporarily residing or sojourning outside this state may be perfected in the same manner as is provided for service of process by publication as set forth in paragraph (1) of subsection (f) of Code Section 9-11-4 or personal service outside the state as set forth in paragraph (2) of subsection (f) of Code Section 9-11-4.
