I chose B. I don't really care what she wears if she is who I like. But in general I prefer cute. I don't want her to look boring, I don't want her to look sluty either. I also don't want her to look like everything is a formal affair. So cute and fun are my vote
I would say D/E would show their comfortable side. If you're attractive regardless of what you wear (clean clothes of course) you will still be attractive and it also shows confidence. As for "A" heck no.
