Adrian Wilson is a strong  safety (6’3″ high, 230 lbs) with the Arizona Cardinals. In this YouTube video (http://www.youtube.com/watch?v=7vL19q8yL54) he is seen to jump a 66 inch high gate with only a short start. The reason he accelerates into the air is:

A. He is a professional football player

B. His feet push against the floor with a force larger than his 230lbs weight

C. The floor pushes against his feet with a force larger than his 230 lbs weight

D. His feet pushes against the floor with a force exactly equal to his 230 lbs weight
