In this scenario, if the man's feet pushing the paddle board down is the action force, then according to Newton's third law of motion, the reaction force must be an equal and opposite force.
The correct answer is: **C. water pushing up on the man's feet.**
This is because as the man exerts a downward force on the paddle board, the water exerts an upward force on his feet in response.
