Given the following code, which methods can use the variable $\_\_$name$\_\_?$

def main$()$:

$$x $=3$

$$y $=2$

$$z $=$ calcData$($x$,$ y$)$

$$w $=$ doStuff$($x$,$ y$)$

$$print$($z$,"",$ w$)$

def calcData$($a$,$ b$)$:

$$c $=$ a $**$ b

$$return c

def doStuff$($j$,$ k$)$:

$$m $=25\%$ j $+$ k;

$$return m;

# The entry point for program execution

if $\_\_$name$\_\_=="\_\_$main$\_\_"$:

$$main$()$

Question $22$ options:

a$)$

calcData

b$)$

doStuff

c$)$

main

d$)$

all of them
