    }
};
int main() {
    Base* ptr = new Derived();
    ptr->foo();
    return 0;
}
  • a)

Which concept is illustrated in the following code?class Base {public:...
The code demonstrates polymorphism by using a base class pointer to invoke a function that is overridden in the derived class. This allows the program to exhibit different behaviors based on the actual object type at runtime. In this case, the "foo" function is invoked through the base class pointer, and it prints "Derived" because the object is of the derived class type.
