![Consider the following code, which is part of a program that maintains student records.
struct record
{
};
int ID;
char last_name[10];
char first_name[10];
int score;
/* This computes and returns the exam average for an array of student record */
double compute_average (struct record [] rec, int n)

return (double) total/n;
Which of the following statements in place of statement will correctly calculate the total of student's score in the array?
O total + rec.score;
O total += rec.score[i];
O total += rec[i].score;
