阅读下列程序，选择哪一个是正确的输出结果 class HelloA{public HelloA()    {        System.out.println("I’m A class ");    }    static    {    System.out.println("static A");    }}public class HelloB extends HelloA{    public HelloB()    {        System.out.println("I’m B class");    }    static{        System.out.println("static B");    }    public static void main (String[] args){        new HelloB();    }}

• A.static A I'm A class static B I'm B class

• B.I'm A class I'm B class static A static B

• C.static A static B I'm A class I'm B class

• D.I'm A class static A I'm B class static B
