Almost any object will create lift if it has some AOA. You can verify

most of us did as kids. If you rotate your hand from horizontal to say
30 degrees relative to the wind, you can create a fair bit of lift. And
most of our hands aren't exactly an ideal airfoil.


The magic question though is that B or N? I found as a kid (I guess I
was bored) that curving my hand resulting in better "lift", which would
seem to implicate B.

Neither, it is C.
