What are the values of array and index after the call to bar?

private static void bar(int[ ] a, int i) {
a[i]++;
i++;
}

int[ ] array = { 1, 2, 3 };
int index = 1;
bar(array, index);

*a.* array = { 1, 2, 3 }; index = 1;
*b.* array = { 1, 2, 3 }; index = 2;
*c.* array = { 1, 3, 3 }; index = 1;
*d.* array = { 1, 3, 3 }; index = 2;
