Consider the following ANSI C program: 

C
#include <stdio.h>
#include <stdlib.h>
struct Node{
        int value;
        struct Node *next;
};
int main(){
    struct Node *boxE, *head, *boxN; int index = 0;
boxE=head=(struct Node *)malloc(sizeof(struct Node));
    head->value = index;
    for (index = 1; index <= 3; index++){
boxN = (struct Node *) malloc(sizeof(struct Node));
boxE->next = boxN;
boxN->va1ue = index;
boxE = boxN: }
    for (index = 0; index <= 3; index++) {
printf(Value at index %d is %d\n, index, head->value);
        head = head->next;
printf(Value at index %d is %d\n, index+1, head->value); } }


Which one of the statements below is correct about the program? 2021 SET 2 || MCQ || 2-mark


It dereferences an uninitialized pointer that may result in a run-time error.

It has a missing return which will be reported as an error by the compiler.


Upon execution, the program creates a linked-list of five nodes.

Upon execution, the program goes into an infinite loop.
