The setting in "The Open Window" influences Mr. Nuttel’s expectations by creating a sense of isolation and unfamiliarity. He is in a rural retreat, which makes him feel as if he is among total strangers. This contributes to his inner doubt about the value of the visit. Given these circumstances and his previous conversation with his sister, he does not expect the visit among strangers to have much value. Therefore, the correct response would be:
He does not expect the visit among strangers to have much value.
