Answer: The correct answer is "The comb gains electrons".
Explanation:
A static charge is induced by rubbing the two surfaces of the material. These materials are not a good conductor of electricity.
The electrons are transferred from one material to the other.
A static charge is induced on a material when the material loses electrons due to friction.
The material which acquires the electrons will get negatively charged.
While combing the hairs by using a comb the combs become negatively charged. Here, the electrons are transferred from hair to the comb. Therefore, the comb will gain electrons and it will get negatively charged.
Therefore, "the comb gains electrons" is true.
