Choose correct constructor bodies to be inserted at line (1).

class Base {
    public Base(String s) {
        System.out.println("Base(" + s + ")");
    }
}

class Sub extends Base {

    private static final String CLASS_DUMMY_STRING = "CLASS_DUMMY_STRING";
    private final String INSTANCE_DUMMY_STRING = "INSTANCE_DUMMY_STRING";

    public Sub() {
          //(1)       
    }

    private static String getClassString() {
        return CLASS_DUMMY_STRING;
    }

    private String getInstanceString() {
        return INSTANCE_DUMMY_STRING;
    }
}
Explanation
You can't use non-static fields, results of non-static method calls, or pointer 'this' as arguments for a constructor of a parent class.
In this case constructor calls super(CLASS_DUMMY_STRING) and super(getClassString()) will be correct.
