Correct Answer: it acquires a
Solution : The correct choice is the second option .
Explanation : "It" is the correct third-person pronoun to be used here in place of "they" , as the pronoun "it" refers to non-living things, whereas "they" is used to refer to people. Also, "acquired" should be changed to "acquire" , as the sentence is in the past tense. This makes the sentence grammatically accurate.
Therefore, the correct sentence is: "When a plastic comb is rubbed on dry hair, it acquires a static charge."
