Answer

Brief Explanations:

Gravitational force pulls objects towards the Earth's center. When the ball is on a slope, the component of gravitational - force along the slope makes it move downhill. Applied force is not present as James didn't push. Drag force acts against motion in a fluid. Friction force here opposes the motion to some extent but doesn't cause the downhill motion. Normal force acts perpendicular to the surface of the slope.

Answer:

D. gravitational force
