In lines 48-49, the narrator states that the North Pole “is an abstraction, a mathematical fiction” and that “no one but a Swedish madman could take the slightest interest in it.” In this context, the narrator is stating that people would not “take the slightest interest in,” or be curious about, the North Pole.
Choices A, B, and C are incorrect because in this context, “take the slightest interest in” does not mean to accept responsibility for, to possess little regard for, or to pay no attention to something.
