Suppose the input for number is 9. What is the output from running the following program?

``` import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter an integer: "); int number = input.nextInt(); int i; boolean isPrime = true; for (i = 2; i < number && isPrime; i++) { if (number % i == 0) { isPrime = false; } } System.out.println("i is " + i); if (isPrime) System.out.println(number + " is prime"); else System.out.println(number + " is not prime"); } } ``` a. i is 3 followed by 9 is prime b. i is 3 followed by 9 is not prime c. i is 4 followed by 9 is prime d. i is 4 followed by 9 is not prime
