Microwave is a subset of Radio and should not be listed separately. My guess is that Wikipedia was used as the source for this quiz. You can see if you look closely at the table that microwaves are not a separate type.
It's complicated. These are the terms that are most commonly learned and taught, so I think the quiz should stay as is. And since its an arbitrary definition, its not like any one way is "correct".
