C looks good to me. Extending an interface to add more methods makes sense.

D is definitely wrong. Interfaces can't implement other interfaces, they can only extend them.

I think A and B are the correct answers. Interfaces can only have abstract methods, and they can't inherit from concrete classes like Point.
