Question 4 Consider the following code that creates four node structures: 1 #include 3-typedef struct node 5 int value; 6 struct node* next; 7 Node; 9- int main(void) 10 t 11 Node a malloc(sizeof(Node)); 12 Node b malloc(sizeof(Node)); 13 Nodecmalloc(sizeof (Node)); 14 Node d malloc(sizeof (Node)); 16 a->value = 1; 17 b->value 3; 18 c>value 3; 19 d->value 5; 21 You want to create the linked structure shown in the following diagram: Which of the following line(s) of code would need to appear at the bottom of the program? ?a->next-b; O d-znext - a a c next - a b->next-c
