The correct option is B anyone
When we speak about more than two persons or things, we must use 'anyone'. Therefore, Option B is the correct answer. Option A and C are incorrect because 'either' and 'both' are used to speak about only two persons or things. Whereas, in this sentence we are talking about more than two places. 'None' means not any of the given options, it's negative in meaning. However, the sentence is affirmative in meaning. So, Option D is incorrect.
