Option (A) does make any sense. It's like just not mentioning Spider-Man was an Avenger (something not truly relevant to his history) and just say "We won't categorize him as an Avenger".

(B) is the only acceptable option of those two.

Charles being a Changeling it's just not mentioned explicitly in his history, but it can be perfectly reasoned when the text event states that "Charles' telepathic powers began emerging when he was still a boy, around ten". So you have Charles' powers emerged before he was a teenager, you know that Changelings manifest their powers at young age, you just do the math.

But, of course, it can be explicitly mentioned. An easy addition of "by his nature of being a Changeling" can be added right after the previously quoted sentence with no problem at all.
