Answer:O methods

Explanation:

Answer 2

0 methods (Option A) is right.

In the case where a class extends another class, the additional methods can be overridden if necessary, otherwise the method can be used as is. However, if a class implements an interface, it must implement all the abstract methods defined in the interface, otherwise they must be declared as abstract which cannot be initiated.
