It is perfectly acceptable to have two references pointing to the same object, so no errors will be generated. Therefore choices a and b are incorrect. Choice d is incorrect since objects are marked for garbage collection only when no references point to them. Choice e is incorrect since references are called null when they do not point to anything. Choice c is the correct answer.
