Answer:
2. indefinite
Explanation:
An interrogative pronoun is a word that is used when we ask a question (what, when, where, who, which, whom, whose, why, how). Indefinite pronouns are those that refer to non-specific beings, objects or places (everyone, something, nobody, etc.). Demonstrative pronouns are those that are used to point to something within a sentence (this, these, that, those). In this example, "no one" is being used as an indefinite pronoun.
