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

```
#include
using namespace std;

int main()
{
cout << "Enter an integer: ";
int number;
cin >> number;

int i;
bool isPrime = true;
for (i = 2; i < number && isPrime; i++)
{
if (number % i == 0)
{
isPrime = false;
}
}

cout << "i is " << i << endl;

if (isPrime)
cout << number << " is prime" << endl;
else
cout << number << " is not prime" << endl;

return 0;
}
```

A. i is 3 followed by 9 is not prime
B. i is 3 followed by 9 is prime
C. i is 4 followed by 9 is prime
D. i is 4 followed by 9 is not prime

D. i is 4 followed by 9 is not prime
