$0$ points possible $($ungraded$)$

Below are several functions and their corresponding function calls. Each function call is assigned to the

variable result.

For which of the following functions the final value of result be None?

$1|$ def some$\_$function$\_1($i$,$ j$)$:

$2|$ print $(i+j)$

$3|$

$4|$ result $=$ some$\_$function$\_1(5,6)$

def some$\_$function$\_2($i$,$ j$)$:

return $i+j$

$31$

$4|$ result $=$ some$\_$function$\_2(5,6)$

def some$\_$function$\_3($i$,$ j$,$ k$)$:

product $=i**j$

sum $=j+k$
