B is correct.
Duplicate default methods named calculateSurfaceArea with the parameters (double, double) and (double, double) are inherited from the types Ellipse and Rectangle
Note: if the class already has the same method as an Interface, then the default method from the implemented Interface does not take effect. However, if two interfaces implement the same default method, then there is a conflict.
