Roger -

Double check, I think that your answer is incorrect. Why do you think your answer is correct?

Hi,
According to me the correct answer is D.
As for C, the objects can still be garbage collected if we have a refernce of that object.i.e. we have islands of isolation wherein object can have reference from other object but these references are just circular and they both refer to each other, not any other thread so both of these objects can be garbabe collected.
About B, we can still have object in memory even if we r not using it.. as long as we do have a reference to that object, that object will not be garbage collected regardless of we are using it or not..
