The correct option is C anywhere
Indefinite pronouns do not refer to a specific person, place, or thing. In English, indefinite pronouns are formed using quantifiers like any, some, no and every. Since the given statement is declarative and the speaker doesn't state a specific place, we cannot use 'where' and should instead use an indefinite pronoun. Therefore option B is incorrect. The indefinite pronoun 'somewhere' is used in affirmative sentences. 'Nowhere' is used in affirmative sentences with a negative meaning signifying absence, but they are not negative sentences since they lack the word 'not'. Since the given statement is a negative sentence, option A and D are incorrect. On the other hand, the indefinite pronoun that is used in negative sentences is 'anywhere', thus option C is correct.
