Answer 1

The option that BEST explains why the hair becomes attracted to the balloon is:

Rubbing the balloon along her hair moves electrons from her hair to the balloon.

When the balloon is rubbed on her hair, electrons from the hair transfer to the balloon, giving the balloon a negative charge and leaving the hair with a positive charge. The opposite charges (positive on the hair and negative on the balloon) create an attractive force between them.
