Need help in this question

Consider the following skeletal C program:
void fun1(void); /* prototype */
void fun2(void); /* prototype */
void fun3(void); /* prototype */
void main() {
int a, b, c;
. . .
}
void fun1(void) {
int b, c, d;
. . .
}
void fun2(void) {
int c, d, e;
. . .
}
void fun3(void) {
int d, e, f;
. . .
}
Given the following calling sequences and assuming that dynamic scoping
is used, what variables are visible during execution of the last function
called? Include with each visible variable the name of the function in
which it was defined.
a. main calls fun1; fun1 calls fun2; fun2 calls fun3.
b. main calls fun1; fun1 calls fun3.
c. main calls fun2; fun2 calls fun3; fun3 calls fun
