A, B, and D are incorrect.
A is incorrect because when the new keyword is used, it initializes the object to a new non-null object.
B is incorrect for the same reason as A, plus the Object constructor does not accept any arguments.
D is incorrect because null() is a made up method and is invalid in Java.
