AP Computer Science A· difficulty 3/5

public class C {
    static int x = 5;
    public static int change() {
        int x = 10;
        x = x + 1;
        return x;
    }
    public static int run() {
        int a = change();
        return a + x;
    }
}
// Call: System.out.println(C.run());

What is printed?

A
$16$
check_circle
B
$21$
C
$11$
D
$22$

Explanation

Local x in change() shadows static. change() returns 11. run() returns 11 + 5 (static x unchanged) = 16.
