When using polymorphic functions(virtual), in order to access the BASE class version of the function from WITHIN the Derived class, one would simply say "Base::functionName()".

For e.g:

class CGeometricObject
{
public:
virtual void toString()
{
// do something..
}
};

class CCircle : public CGeometricObject
{
public:
void toString()
{
CGeometricObject::toString();  // call BASE class version of toString (first)
}
}

If we take the following class definitions:

class CGeometricObject
{
public:
virtual void toString()
{
 printf("I am in base");
}
};

class Circle : public GeometricObject
{
public:
void toString()
{
  printf("I am in derived");
}
};



then since we are not declaring pointer to object for circle object , so we can not use '->' operator to call function.
So 'D' option would be right if we call funtion in this way

c.GeometricObject::toString()
