The gender-neutral plural pronoun is "they". To determine this answer, you can first understand that pronouns are used to replace nouns in a sentence, allowing us to refer to people or things without repeating their names. In English, the pronoun "they" can be used to refer to a group of people or things without specifying their gender. This is different from pronouns like "she" or "he" which are gender-specific and refer to individuals. The pronoun "it" is also often used, but it typically refers to inanimate objects or animals. Therefore, the correct answer to the question is "they".
