Option B is correct. All references to theBarobject created on line 6 are destroyed when a new reference to a newBarobject is assigned to the variablenewBaron line 14. Therefore theBarobject, created on line 6, is eligible for garbage collection after line 14.Option A is wrong. This actually protects the object from garbage collection.Option C is wrong. Because the reference in thedoBar()method is returned on line 7 and is stored innewBaron line 12. This preserver the object created on line 6.Option D is wrong. Not applicable because the object is eligible for garbage collection after line 14.
