The syntax of the call line is:

    #+call: <NAME>[<HEADER-ARGS-FOR-BLOCK>](<ARGUMENTS>) <HEADER-ARGS-FOR-CALL-LINE>

So, you should add your option either in [] after the name, or at the end of
the line -- I'm always hesitating about where to put the right stuff (not so
enough clear yet in my mind)...
