C Programming Which of the following statements are correct about the program below?#includevoid main(){ int size, i; scanf("%d", &size); int arr[size]; for(i=1; i<=size; i++) { scanf("%d", arr[i]); printf("%d", arr[i]); }} The code is erroneous since the values of array are getting scanned through the loop. The code is correct and runs successfully. None of these The code is erroneous since the subscript for array used in for loop is in the range 1 to size. The code is erroneous since the statement declaring array is invalid. The code is erroneous since the values of array are getting scanned through the loop. The code is correct and runs successfully.
