Clayton is a water skier who recently started to feel a sharp pain in his right knee. One of his favorite moves he is trying to perfect is to ski up a ramp, fly through the air and land as far as possible down the water. His body mechanics may be contributing to his knee pain because he: (2 points)

a
Has a wide stance with his knees parallel to balance on his skis at takeoff

b
Has his weight distributed evenly when landing on the water

c
Is keeping a low center of gravity by bending both knees when approaching the ramp

d
Is landing on the water with a straight right knee and slightly bent left knee
