Hey there!
When you breathe in, your body is inhaling oxygen and converting it into carbon dioxide, or CO2. When you exhale, your body is getting rid of that CO2- because usually, it's not good to inhale.
Therefore, the answer is C. Your body has CO2 in it, and needs to get oxygen to oxygenate the blood to give to places like the brain that need it most. 
Hope this helps!

On the other hand, the color of petals do not really have effect on the wind pollination. Therefore this explains why wind pollinated flowers usually have small or dull colored petals.
