Correct Answer : D
The object I of the class Integer is created and the method string() is called. Then, object t of the class Integer2 is created and initially t.x stores a default value of zero. Then when the method fix is called with parameter t and the value 42 is stored in x variable of the object tt which is same as t. Since tt is returned and the return value is assigned to t2, both t2 and t point to the same object. Hence the values of t.x and t2.x will be 42. Atlast, the required values are printed.
Also note that, since the Integer class is created here in the default package, it does not clash with the wrapper class java.lang.Integer.
Hence, the answer is D.
