b) electrons jump onto or off the neutral ball when a charged object comes close
Explanation:
What causes a pithball to move is when "electrons jump onto or off the neutral ball when a charged object comes close".
The pithball electroscope is actually used to test if a body is charged or not. When a charged body is brought near the pithball, the ball moves. The movement of that charged body reveal that there are electrons it is carrying.
