Solution

The correct option is A move away from the body
A pith ball electroscope helps in identifying the presence and nature of electric charge present on an object. When a positively charged object is brought near a positively charged pith ball electroscope, as a natural reaction, the two repel each other. So, the pith ball moves away from the object.
