A subclass can inherit both methods and instance variables from its superclass, and it can also add its own methods and instance variables. It can also override the inherited methods if necessary. Therefore, option D is correct. The other options are incorrect because they place restrictions on the subclass's ability to inherit or modify the behavior of its superclass.
