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. This transfer of electrons results in the balloon gaining a negative charge (since it has gained extra electrons), while the hair loses electrons and becomes positively charged.
