A 5. What happens on the floor when the force of your body pushing down as you stand on it?
a reaction to the floor pushing up
b. matched by the floor pushing up on your body
c. less than the reaction force applied by the floor
d greater than the reaction force applied by the floor

my choice is B

Explanation:

matched by the floor pushing up on your body cuz technically the body has greater force applying on the floor so the floor reacts by pushing your body up

(not clear so thanks, sorry and hope I was helpful)
