Consider a C function with the following declaration: void spawn_larva(int a, int b, int c, int d);
Assuming spawn_larva has been compiled for an x86 IA32 machine with 4-byte ints, what would be the
adress of the argument b in terms of %ebp in the stack frame of spawn_larva?
(a) %ebp + 4
(b) %ebp + 8
(c) %ebp + 12
(d) %ebp + 16
(e) %ebp + 20
