Function Overriding in

Polymorphism

Why is function overriding an example of polymorphism?

Function overriding has a single interface $($the function name$),$ but only works with a single data type $($the derived class$).$

Function overriding is not an example of polymorphism, it is an example of inheritance.

Function overriding has a single interface the function name$)$ and works with different forms $($the base and derived classes$).$
