Answer 1

The correct response is:

The balloon’s charge became negative, and the hair’s charge became positive.

When the student rubs the balloon on his hair, electrons are transferred from the hair to the balloon, giving the balloon a negative charge and leaving the hair with a positive charge. This difference in charge causes the balloon to stick to the hair.
