Answer:
Object B has more charge than Object A
Explanation:
Generally, unlike charges attract each other and like charges repel each other but it happens in a very rare case when like charges attract each other. It is so due to charge difference between the objects.
In the given example a positively charged ball moves towards positively charged object B because object B has more charge than object A and the ball. Due to large difference in the charges between two positive charges, positive charges are displaced at opposite end and object B get concentrated with negative charges that allows ball to move towards Object B.
Hence, the correct answer is "Object B has more charge than Object A".
