This pointer doesn't works in static member functions since the static member functions doesn't require an object to invoke the member function.
And display member function function is not a static member function it is normal member function so if we call display we need to create a object then it call.

Because the display is just a member function of class. It can be called in main fn by creating object. Only the static fn or variable called by class name and scope resolution.

Because Display() is non-static method and non-static methods are always called using object.
eg :-
IndiaBix obj;
obj.Display();
Correct way to call.
eg :-
IndiaBix obj;
obj.Display();
Correct way to call.

Replace int main() part by following Code.
int main()
{
IndiaBix obj;
obj.SetData(33);
obj.Display();
return 0;
}
Output : 33
int main()
{
IndiaBix obj;
obj.SetData(33);
obj.Display();
return 0;
}
Output : 33

Can not call display() function without object! Because display() is not declared static.

We can't call non static function without creating object. So D is the right option.

Because display is not a static function, it cannot be accessed by class name.

The class Indiabix don't have an object for call a member function dispaly().

@Pooja is right. Only static function can access static data members.

We cannot use scope resolution operator in main function.
