Neither and nor are used together.
Either and or are used together.
B uses neither and or together, so that is wrong.
C uses either and nor together, so C is wrong.
D uses neither and or together, so D is wrong.
That leaves A.
A used neither and nor together, which is correct.
So the answer is A.
I need the story to see if that is the correct one.
A bounce room. it's Willie Wonka and he has money and all these other rooms why not have a bounce house room? it would be fun if children and adults can go to the factory and bounce around.
