Look at the following code:

Scanner keyboard = new Scanner(System.in);
int studentGrade = 0;
int totalOfStudentGrades = 0;
while(studentGrade != -1)
{
   System.out.println("Enter student grade: :");
   studentGrade = keyboard.nextInt();
   totalOfStudentGrades += studentGrade;
 }

In the loop header: while(studentGrade != -1), what is the purpose of "-1"?
A) It is a sentinel.
B) It tells the program to give the student a grade of -1, if he does not have any grades.
C) It initializes the count of the number of grades.
D) If the grade is not -1, the while statement will not be executed.
