Given the following lines of pseudocode:

def server$\_$temp$()$:

temp$\_$val $1=40$

return temp$\_$val$1$

def start$\_$backup$()$:

disk$\_$list $=$ 'list: track', track$\_$num, $\text{'}/\text{'},$ sector$\_$num

temp $=40$

if temp $==$ server$\_$temp :

global temp$\_$val$1$

temp$\_$val $1=25$

return temp$\_$val$1$

What value will temp$\_$val$1$ be if start$\_$backup$()$ is called?

A$.$ temp$\_$val$1$ is never reached in start$\_$backup$().$ Therefore, temp$\_$val$1$ will be $40.$

B$.$ start$\_$backup$()$ is making a recursive call, values in variables will never change.

C$.$ temp$\_$val$1$ will be $40.$

D$.$ temp$\_$val$1$ is changed to global as last line code to be executed. temp$\_$val will be $25$ if start$\_$backup$()$ is called.
