A Correct answer
Explanation

Private methods are not visible to subclasses and therefore cannot be overridden. A subclass can only override public and protected methods. An overriding method cannot declare more checked exceptions than the overridden method. The parameter list must match exactly (same number and types). The return type must be covariant (same type or subtype).
