Answer 1

In dynamic binding, derived class's function overrides the base class's function.

But in static binding,
If a function is final, private or static in a base class, that function can't be overridden by the derived class. Now when overriding doesn't occur, the function in the base class is called.

In short:
In dynamic binding, type of object is determined.
In static binding, type of reference is determined.
