Jasmine put her comb near a stream of water after she had combed her hair. The water moved towards the comb. What is making the comb attract the water?

• Combs are like magnets; they attract water.

• The comb gained electrons, making it negatively charged, which attracts the neutrally charged water.

• The comb gained protons making it positively charged, which attracts the neutrally charged water.

• The comb gained electrons, making it positively charged, which attracts the negatively charged water.
