There is no object to use class members.

Non static method can also access the static data.

We cannot use scope resolution operator in main function.

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

No. Only static functions can access static members.

Why is it compile time error ?

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

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.

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