Answer 2

I think it's B my friend say's it's A.

Answer 3

I honestly dunno :/ A makes more sense to me, but that's just a guess.

Answer 4

A for sure! You wouldn't think your body's natural response would be to pull your blood away from your skin, because you would think it would want to warm you up by pushing it towards it, right? Well, what is even more important for your body to keep warm is your vital organs. When you're cold, your body is going to automatically draw your blood inwards to warm your organs. It is a protective response. Which is also why your cheeks get really red when you are hot/sweaty from running, etc. Your body pushes your blood away from your vital organs (well, a certain amount haha) in attempt to keep them from overheating. That is as simple as I can put it. Went over it in gen cell bio recently. :)
