Solution

The correct option is B
They acquired different kinds of charges

We know that objects acquire charges when they are rubbed against another object. We also know that like charges repel and unlike charges attract each other. In the above experiment, the balloon has acquired a kind of charge that is opposite to the charge acquired by the ballpen refill. As unlike charges attract each other, the balloon and the refill developed a force of attraction between them.
