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.

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

We cannot use scope resolution operator in main function.

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.

Non static method can also access the static data.

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

No. Only static functions can access static members.
