Answer:
"Anyone" is an indefinite pronoun.
Step-by-step explanation:
Indefinite pronouns are those pronouns that do not specifically refer to anyone or anything in particular. They can represent either countable or uncountable nouns, irrespective of any specificity.
On the other hand, a demonstrative pronoun is a pronoun that points to a specific group. It demonstrates the noun or objects it refers to.
In the given sentence, the pronoun "anyone" is an indefinite pronoun as it refers to no one in specific. It rather refers to a case of anyone, whoever that may be, and not a particular person.
Thus, the pronoun "anyone" is an indefinite pronoun.
