I agree with Ex on that.
That kinda questions usually come from girls who aren't self confident (or at least they are not at this particular moment when asking). There's no wrong or right answer here, no matter what you say, pay attention to your body language, (if you want her) just lean an inch closer, that would immediately give her some good vibes and most probably she wont need to hear any kind of verbal explanation.
We all want apples and carrots
