Final answer:
The correct answer to the question is that the positively charged hair would be attracted to the negatively charged balloon and would rise up to meet the balloon (Option C).
Step-by-step explanation:
The result of rubbing a balloon against woolen fabric or your hair would be that the balloon becomes negatively charged and your hair or the fabric becomes positively charged.
The static electricity created causes opposite charges to attract each other, demonstrated by hair standing up towards a charged balloon or the balloon sticking to a wall after being rubbed.
This phenomenon is due to the transfer of electrons, which are negatively charged particles, from your hair or the fabric to the balloon, leaving your hair or fabric with a net positive charge and causing an attraction between the two.
