I'm not sure, but I think D) is incorrect because XML Schema allows for redefining elements.

You know, this reminds me of that time I tried to define a new element in my schema and ended up breaking the entire thing. Definitely don't want to make that mistake again. I'm leaning towards option C as well.

I agree, making changes to the schema can be tricky. Option C seems like the safest choice.

I disagree, I believe the correct answer is C) because it uses xs:redefine to change the schema definition of cellPhone.

Woah, wait a minute! Did you guys see that weird 'wvwv' in option B? I'm pretty sure that's not a valid URI for the W3C namespace. I'd steer clear of that one.

Thanks for pointing that out. Option B should be avoided due to the incorrect URI.

Yeah, I noticed that too. Option B is definitely not a valid URI for the W3C namespace.

I agree, that 'wvwv' in option B doesn't look right. It's probably a typo.

I'm not so sure about that. What if we use the 'include' statement instead? That way, we can keep the original schema definition and just add the 'cellPhone' element. Just a thought.
