Question: Consider the following skeletal C program: void fun1(); //prototype void fun2(); //prototype void fun3(); //prototype void main() { int a,b,c; } void fun1() { int

Consider the following skeletal C program:

void fun1(); //prototype

void fun2(); //prototype

void fun3(); //prototype

void main() {

int a,b,c;

}

void fun1()

{

int b,c,d;

}

void fun2(){

int c,d,e;

}

void fun3(){

int d,e,f;

}

Given the following sequence and assuming that dynamic scoping is used. What variables are visible during execution of the last function called as listed below? Include with each visible variable the name of the function in which it was defined.

(3pts)main calls fun1, fun1 calls fun2, fun2 calls fun3
(3pts) Main calls fun2; fun2 calls fun3; fun3 calls fun1
(3pts) Main calls fun1; fun1 calls fun3; fun3 calls fun2

Thank you ahead of time for your help.
