下面程序运行时，第3条打印语句的输出结果是（）。public class Foo { static int i = 0; static int j = 0; public static void main(String[] args) { int i = 2; int k = 3; { int j = 3; System.out.println("i + j is " + i + j); } k = i + j; System.out.println("k is " + k); System.out.println("j is " + j); } }
选项：

A: j is 3;
B: j is 2;
C: j is 1;
D:j is 0
