Its A cause x-rays is considered harmful
abruzzese [7]3 years ago

I would say the answer is A because X-rays have more radiation just enough for you not to get effected by it, while microwaves if they do not have those type of little black holes sheet on the plastic door then it would effect you thats why you shouldn't get too close to the door.
