Final answer:
The frictional force acting on a ball rolling from north to south is in the opposite direction of its motion, which is north.
Step-by-step explanation:
The question involves understanding the direction of frictional force acting on a moving object. When a ball rolls along the ground from north to south, the frictional force that acts on the ball is in the opposite direction to its motion. According to Newton's First Law of Motion, which addresses inertia and friction as an external force, friction always acts in the opposite direction to that of motion or attempted motion between surfaces in contact. Therefore, the correct answer is c) North.
